The Knife In Hilchos Kashrus - Rabbi Yakov Zev Smith

couple of times with a knife [Music] like to welcome everyone to today's share from our viewers that's mitch lita on the knife and who has a cachers genie has sack and douglas catchers upgrades this is sponsoring a shirt called shiratara 718-851-8651 or email ist shivenet.com it was like this year when er and someone cut a roast with the milk knife a question what to do it's a very air vm dip you need the roast where the shiloh a while ago was a regular shabbos someone cut up carrots and pasta for chicken soup and they cooked the chicken soup only afterwards really they had cut the carrots and tossed it with the milk a knife and then we had a question all the time people ask this about buying watermelon or fish in a non-kosher store if you notice the common denominator is a question that come up all the time or tariffs but specifically it's not a question of bishop per se but it's a question of a knife a knife cut up a roast a knife cut up with carrots and these questions come up again every arab shabbos when the person cooking especially this year we're having another heir of shabbat saraswas we heard a shiloh with someone use a food pro a flay sugar food processor and cut up onions and put it into a milky dish so you tempted to ask in all these questions a food processor or a knife what's the problem we're assuming the knife is clean so how could the knife affect the food that way it's cut so we have to learn a a short piece of gemara that's really packed with information for our suggest in the very end of kufura bays you subtitles a radish with a flake sugar knife you can eat this radish with milk is always a milk food so in other words you have a power of a radish and you cut it with a fleischer knife and the gemara is assuming that the knot that the radish becomes flashing now that's a plio because maybe the knife is clean and more so but there's no doubt about it if you cook loction powerful auction of course in a flash sugar clean pot and you add a cheese all agree the cheese is causing the election and cheese is kosher because essentially lakshman cooked in a flake sugar pot remains powerful so white is a knife which is less than cooking how could that make the snail the radish flashes but the cash is deeper because the gemara's next words are that if you cut a squash then you just peel the outside and you can use it as it is manish tana why is squash different than radish more so the gemara says but turnips even more mother so we have a obvious question to deal with why is a radish become flay six and why is squash any different so yes and rasheed gives us the guidance for not only this kimar but the whole sugya says rashi the following rashi is bothered by our question why is luxian different than radish so it says rashi a stamp pot that you cook in or plate for that matter is clean so if you cook luxury in a clean flavor sugar pot luxion is unaffected because the pot is clean okay this blaze but the bliss gets it goes into the water and the oxygen luxion cooked in a flashing apart remains powerful but and here's the two lines for today aval sakin pam noon is courage or love the knicker a knife that typically cuts meat or any flay sugar item leaves a an unnoticeable flake sugar residue a sort of a film of flakes you cut meat you'll see on the knife there's a greasy grimy substance which is not noticeable it's not like a piece of meat but this place shake my moshes says rashi now you have a knife that's flay shakes it's not the bliss that i'm worried about it's the mamashes on the knife now when you take this fleischer knife that has a layer of plastics on it when you cut the radish habi noise what you're doing is you're putting a little flash sticks onto the radish and this is one unique feature of a knife a knife has shamnoonis kim saying a knife that cuts things retains a noticeable or unnoticeable flay sugar residue and if it's a military knife it has a cheese residue once you assume that there's a little bit more moisture on the knife then even if you use a knife a day and a half ago so it's an annie benjoymay and the belias are stagnant but my muscles remain vomatious so when you cut the radish with this fleischer knife you're putting some flaccid onto the radish i'll give you a mushroom a beautiful mushroom lasagna oisin a person takes strictly power of a piece of khala and puts and butters it with br with butter he smears butter on this challah is the khala milkrikes yeah why i didn't cook the color there is what i mean you put milk you put butter on bread it becomes milkfix so if you have an inflamed sugar night and this mamash is on it when you cut the radish you're putting flashes onto the radish sokkiva ega and our simmons simmons said that above seeds cotton based coating of terracottas and i saw the is the same thing you could see the reality of this because take a knife that you just cut meat with and run water over the knife it doesn't roll off smoothly like a clean item because this sham noon is talk upon of you see a resistance because the water is sticks to the flagships the residue if you take a butter knife and you run water over a butter knife you'll see the water doesn't roll off because a little bit of the mamasha stays and that is attracted to the water that's the problem the knife itself is not a problem we'll soon see a clean eye if the car is not a problem but if you cut meat there's a meat residue now you smear the meat residue onto the radish understandably the radish is flay six the point is and that's we'll soon see that a stump knife is not clean for some reason you see this in rashi they weren't so particular to clean the knives maybe they don't have enough water maybe they didn't mind but the myself when you had a flaccid knife it had some residue on its tam sakin and i'll illustrate this and those that learned that you had this not not long ago you might have not understood it but now you will the gemaran bayer daft zion discusses making an error of tafshilan you need minimally accusations for the af to work and the marriage has different options zelda one option is we take a knife and there might be a kazias of some newness on the knife could you imagine a plain knife you know when it's snowing the expect accumulations up to an inch so on a knife expect accumulations up to a casios they had a causalis of fat on a flashing knife and the machaba quotes it the tough of have zion you could use a knife that has a kazaas of accumulation again they they weren't mocked it for some reason to clean their knives now because ice is not that big this is an olive but can you imagine having a mammoth of a kazaas the size of an olive on your knife so this is the concern about a knife stomp stomp you could assume is clean but a knife has residue plus i must mention as we'll soon see knives had gumas like crevices it wasn't the fine quality that we have today and therefore they were cracks and crevices and the accumulation of the fat of my mushrooms went into that but the myself this is the understanding of the snowing and the focus is sakin the point is the knife has mamashes of lasiks now you cut the radish you put the flake sugar residue onto the radish understandably the radish is treated as flavisix ah now we understand the answer to our question when you cook luxury in a clean flake sugar pot there's no mamashes so it's not the terra the luxian is essentially powerful we don't mix the katrila but it's powerful but a knife a knife has felices a this is a perfect i'll give you a perfect example of an ice in so what would you say to a person by a shabby suit which is flashing typically he cuts the color with the milk knife if you say it's not traditional it's not heimish you have to have a special color knife and the shabbos knife but you wouldn't see a problem with that but listen to a majaba and pay test valid you're not going to cut cheese with a flay chicken knife even cold cheese and loya to cut kala with a flake chicken with a milky knife let's say turn the flavor soother now i understand you can't cut cheese with a flake chicken knife but why can't i cut khala with a milky knife the turret says like we explained it's beautiful when you're cut with a flat with a milk a knife we assume there's a little bit cheese a little bit butter whatever it is so you're putting milks onto halo and then you're going to eat the challah with full asics it's the same problem as the basios of quoting the ramban and that simmons says because this the the knife has residue of the other men and you're making the kala milks and that's the same like cutting a radish with a flake sugar knife you're depositing ratting plastics on the radish so the point is that here the focus is on the word sakin stam saken cham nunes taco pon up and that's the problem now here we would wonder are very good but let's say i told you i cut the radish i'm certain it was a clean knife no my muscles i scrubbed it i still hold it it's clean no my moshes remain unaffected also needs hezbo if you're telling me stam sakan makes a problem with the radish so why did the murray say that squash is different and why is turnips different so we have to continue in rashi rashi is it's not a second shot it's an additional shot actually adding to the first shot mr [Applause] now this is really the last part of this beautiful puzzle let me explain this what rashi is saying is that a radish as opposed to squash is a dovahkhar dabakar is a sharp food troll kharif is a sharp you know dip kharif is a shark food the mathias is as the gemara says in our dessert atlantis a sharp food has the chemical ability of revitalizing even stagnant bliss when you cut a food with a aina benjamin the food is not affected by the knife but as the mars says if you cut a a sharp food hilt is a sharp food with even an inupin you might the sharpness the it's a chemical reaction of the sharpness has the ability to extract that blea and revitalize it and make it a real mamma as if it's a real mamas as if it's a benjamin plus the fact is when you cut something with a knife there's akinas rashi uses the term and the pressure of the knife the friction when you cut a rat which is a hot item so that takes out more believes now this rashi is expecting us to know shas so he expect us to know the runaway desire regarding a sharp item and expects us to knock them on the customer that when a person sharks an animal with a trayfor sake the animal might become traits at least the part where he checked it i what's wrong so the gemara says the you need some pressure so that is able to take out the bleois of the tree for knife and make part of the animal trait so there are two independent halachic factors number one dove kharif makes more problems with police aquina is able to extract police and when you cut the radish with a clean knife an innocent clean knife you have both factors compounding the problem first of all the knife is a double it is aquino you're cutting radishes also it takes out the players from the fleischer knife so even if the knife is clean there's no my moistures they're still bliss so here by an innocent act of cutting a radish with a clean flake shake a knife takes out the bliss from the knife even the enemy benjimai and puts flagships into the radish no a fleischer radish is placed as simple as can be and that's what the sukhonorak says in fact we find this in very much negaya i'll give you two examples imagine a person cooked an onion in a trayfoot pot a clean pot i don't know why but he cooked an onion he didn't cut onion he put it in hole he cooked the whole onion in a trayfor pot which is clean no meat no traif is floating around so this is the entire onion is awesome why is the onion awesome there's no more moisture the felicity of treve terret says onion is a double curve it's able to extract the bliss of the pot and it pumps trey fables into the onion no the onion is straight kool-aid drink so there we see that dove harv works with el dorado imagine in the olden days a person wanted to buy crane horseradish more on pesach and he has a local gayisha farmer who sells so goes to the farmer give me a piece of crane but you have to be you have to be careful because if the goyisha farmer caught the crane the horseradish the root with the tray for knife even if it's clean the motor is uh that crane is awesome ah it's clean it's not hot but since moderate chain mold is a double chorizo it's able to extract the tarpon of the of the knife even the knives in any banyonline so the place can say make sure the guy pulls it out either with his hand or uses a casino a hole a rake but if a guy cuts plain horseradish with a tray for knife the horseradish is straight ah you'll say there's no bishop so what but this is akina that's aggravating the situation no mamasis no heat no bishop so you have two independent factors one is the fact that it's a double kharif one is the fact that and our innocent has both of them so let's just review what we learned something very simple if you cut a snowing with a knife that has dirt that's dirty that has my mushes so obviously it's a problem you don't have to come on to anything any fancy swarm it's a flash chicken radish because you put flashes on it but even if it's clean you have dulce de of together with the fact that it's a double kharif and it's and the radish is considered flagships one point i want to mention before we apply this to myself and that is let's let's okay fine i understand so i cut a radish with a flake chicken now if the radish is flavored how much of the radish is flavisix is the whole thing flagships it's only a little bit now what do i mean to say that is when you cook an onion let's say in a tree for pot so the whole onion is affected because bissell goes into the entire food how far does dava kharif say how far does it penetrate so we might say bishop affects the whole food maybe double carve is only the outer layer and that's the fact the sheet of the machab inside the olive that when you cut a snowing with a flay sugar knife it affects kadena tila just about an inch of the surface it goes an inch and not more explains but that's all it could do kadena tila zelda it's like bishop and and affects the entire s9 so according to the ram more if you cut a radius with a flash sugar knife it's entirely flagships if you cut it with a tray for knife it's entirely tray and of course if you have shishman soon see that's okay but typically a small radish would be considered according to our more entirely clay chicks and it's very positive just like the davakhar we said earlier speaks about the the crane being trade the radish is considered kool-aid flagships now now let's apply this lemis okay and we'll start with the simple shiloh a person had a food processor and the given was that it's flagships what i guess he he what he did was he uses to to to process hot meat but i didn't ask any questions he said it's a play sugar food processor it was and he processed a lot of onions and put them into a milk dish and cooked it the onions with a milkhiga dish so unfortunately this is a problem because the onions are considered play shakes i the food press was used first last week anybody but this is the heart and this is besides that is blades but the heat of the machine really makes it a problem and you have to treat the onions as flake shakes now flake sugar onions and milk is a very bad combination and if there's no shiishin which typically there isn't this would be basala a real bastard a person cut carrots or parsnip and afterwards realized that he used the milk a knife and he stopped and his first question is what do i do so the rub should say well tell me what type of knife did you use so let's say he says i know for a fact it was a clean eye i took a milky knife out of the drawer and in my house drawers are clean knives we'll soon see that's true so he cut a rat a cut and add a radish he cut a carrot or a pasta dipper with a clean milk a knife so the choir there shouldn't be any problem because there's no way to make the carrot any different the knife was clean there's no sham nunes i'll say wait a second maybe this akina the fact that you have that you caught a carrot you need some strength maybe that would affect the carrot it would make it uh milk like the knife was so the mice it's not logical how how does it what is affected without heat or without kharif doesn't affect so so therefore this would not be a problem the only issue here is that if the knife was not clean he just used it to cut cheesecake and now we used it to cut the carrot so now we have a problem of my moshes in other words when you put on your torah eyeglasses you will see an innocent carrot that has a smearing of cheesecake exactly what happened you cut cheesecake then you cut the carrot where did the the salmon is go onto the carrot but it's not the end of the world either you could have the carrot with milk or if you want to use it for your chicken soup wash it off easy come easy go it's no bliss there's a little of a mamas of milkies on the carrot so wash it off residue doesn't penetrate and it doesn't basically go anywhere however if you cut a radish at double kharif so then it went in the blue is swimming but here there's no oblivious because it's not hot and it's not curved it's just mamashes so wash it off and that's if you cut the crane with a tray for knife so that's like bishop but if you cut a non-horrif carrot and there's no bishop so basically you deposit a little bit my mush is on the carrot so wash it off and the gateway just like we'll soon see if you cut challah with a milk a knife it doesn't become tray scrape off the milk here also do the same the problem is if he realized his mistake after he made the chicken soup so he put in the carrots and the parsnips that were cut with a military knife what's that so again the rubber say tell me was the knife clean he goes i think it was clean okay the soup is closed no shiloh but let's say he said no no i used that remember i used a knife a minute ago to cut the cheesecake so now he has the problem but it's not as serious as he thinks it is because the little bit of my moshes on the carrot didn't make the carrot milkfix it's a power of a carrot that has a little bit of milk so try to figure out how much milk could be the most on the carrot a little amount no and the soup is a big soup so even if there is military the military is bottle in the chicken soup and you count all the ingredients and it's like a type of chocolate that fell into a chicken soup and the loch is mother brittle and something but zika is let's say he took a the same knife and cut a horseradish a tray for horseradish and put it into this soup then he said hector saurus you need shisham kaneget the whole horseradish horseradish is awesome but here it's a simple mamas so it's probably bottle so let me be very clear when you have a hard vegetable carrots and parsnips turnips also and if it was a clean eye the vegetables are unaffected if it was a knife that had my mushes of milk is let's say wash it off use it for the soup if you didn't wash it off use it for the soup with the avid as long as you know this shishim it is mutter now let me ask you another question and we'll get clarity in the next stick of the gemara a person cut a tomato and he wants to make grilled cheese he puts the tomato on the bread and he puts cheese on top of the tomato after he did this he realized that he used a fleischer knife to cut the tomato so the question is the tomato was caught by a flaccid knife and he's putting a piece of american cheese on top of that he didn't yet drill it but that's not a good combination so the robot say well tell me what kind of knife place your knife was it clean took it from the drawer okay so it's not a problem there's no prob no transfer oblius from cutting a a tomato with a fl with a flake chicken knife you shouldn't do it with a hat but once you did it it should be okay but let's say he used the flags you can either they just cut a rose with and there's a little bit of residue some noon is talk about this of this knight so now he has a serious problem a thin layer of flagships a piece of cheese that's we called in allah but hollow i mean a thin layer is a little bit but it's still boss up shamnoon is a bust like bossa bossa holla is a terrible combination so avadi should take off the cheese and scrape off any my mush that might have gotten the cheese and if he does a good job the rest is multi but this is a problem of my mushes of boston bacalha had he grilled the the this um combination he has a problem about the bachola unless he's certain that the sham nunes of basa is bottle of the cheese which is not always the case if it's a thin piece of cheese and there might be my marshes but the point is when you have a situation like this mamas and cheese is a very bad combination now here's my question let's say fd cut the the tomato before he put the cheese on it he thought i used the flai chicken knife mamas just he runs to the roof what should i do it's a restaurant if you want you could have the tomato for flacci kasappa no probably not but he wants he needs it for his uh grilled cheese so washing it off should be the eighths up like you wash off a carrot but here is a technical problem and that is that when you wash it for carrot it gets clean when you wash off a soft juicy tomato or any most vegetables for that matter washing embeds it further into the vegetable and makes the problem more of a problem so you're basically pushing the little bit of residue into the cat into the into the tomato ah so what do you do this is the next stick of the gemara and that is the amount of contrast is synonym to a squash squash is similar to tomato that it's soft and juicy so then technically all you have when you cut this wrap this um squash a little film of flakes so really you should be able to wash it off but it's not gonna work so what do you have to do scrape it off there's no blius but my washes will not go off with washing so this is the beauty of the next stick of the gemara it's not a stirrer if i carry it just two different outlooks when you have a a hard piece of carrot or parsnip or turnip washing is enough but a soft juicy vegetable or fruit will soon see washing won't do the trick and therefore you need a little scraping to get rid of it and that's the surrender and sadly and the tas and shaft both expand like i told you in other words had it been a problem of it spreading more and more so then maybe scraping won't help but it's not spreading it's cold there's no bliss it's just the actual mamasis so a hard vegetable washing works on a sore vegetable you have to scrape to get it off the surface says in sif khafalif that today includes most vegetables because they're soft urger kiss and kirbys he calls it most vegetables are really soft and juicy as opposed to a carrot pasta that's hard now la mysa now we understand very nice that manish stannis knowing and squash the liquid manustana squash and turnips is also beautiful because turnips is that hot vegetable that washing is okay now when you have to wash a carrot the poison advised don't wash it with hot water because that might again further the problem it might make the glia not to be the mamas go into the carrot wash it with cold water and also when you have to scrape the tomato let's say you have a tomato that has a little buffalo residue you want to scrape it what should you use so it's probably better to use a flake sugar knife to get off the flake sugar residue and it won't affect the status of the tomato using a milky knife the scraper flash is not a good idea now when you cut chala for a milligram for with a milk a knife and you want to use it for shabbat soother so that's a problem because shabbos will is flagships so you shouldn't have done that not to do that awesome you know awesome means awesome because you might eat this this milk with flagships you know some zombies to always be known the fact people like to say the word he says why also not awesome i'll say awesome but here the shochundarak says the word asa twice it's also to cut parvakhala with the milk knife because it might be mamas that makes the problematic in other words you can play around with knives but let's say he did what's us and he cut the khala with the milk knife so not the end of the world says the prima goddin don't wash the khala that's going to make it worse scrape off the layer of the khala grab if you got you cut a a crusty part of it so maybe you could wash it off a hot crust i mean depending on the materials but color is like a soft soft juicy vegetable you can't wash you have to scrape it problem is once you made this the fret this grilled cheese with the tomato before washing it then you have a real concern of bastard you have to make sure the shisha and not always this if you cut salad with a flake sugar knife so not a problem right so the you have to chew and if it was not clean it might be considered flavors if you added cheese then you have a problem you're adding cheese to a a flake sugar salad so you have to use big be on top of it before you add the other mint make sure that the salad was cut right we had a question someone knows for a fact that he cut the vegetable with a knife it was definitely the wrong knife it definitely was a milkhiker knife he's not sure if it was a dirty knife that was just used or a clean knife in our times so when you learn the suggest you see it all over in fact the whole simon sabic v islam sakin is dirty doesn't have to say it rashi said it come out stamkader is clean and stamp stocking is dirty the assumption like i told you earlier was they didn't clean knives they let it accumulated it dried then it caked on you could have because it's it was a interesting world because of some newness is not done we are more mephonic we have more water to be able to wash and stam sachin he assumes can be considered a clean but he makes an important distinction if you took a knife on the drawer you have a right to assume it's clean because where people menstrual people we put knives in a jar that are clean but if you picked up a knife from a countertop and a busy kitchen you don't know what it was if it's there it didn't walk out of the drawer you used it so it makes the sense that the rub has to be careful to inquire what's going on a stamp socket from a dishwasher from a drawer we soon was clean i mean if the dishwasher was working of course but a stamp stacking on a countertop and a busy year of shabbos even a regular day if it's there it was used so you're making meat you're making cheesecake and you cut through and looking like and you can say now if you cut meat you have to assume that sam sakin on account up is considered very mestabra and of course that's the way it works in other words regarding say stam cayley's anybody that doesn't change but regarding a sakin it used to be samsakhin is considered some nudist and today sacking a draw is not a problem a person listen to this child to see you'll see what it means the knife in allah a person has only a milky knife and he wants to cut khala for they for the shabbos suit them so he looks at it and it's clean so what's the problem he would say come on that's nervous what are you worrying about it's not a horrif it's not hot what's the problem it's a clean melaka knife but it's not postured at all as i told you the shock and pay test downloaded you know to cut cheese with a flay chicken knife and now they cut hala with a milky knife for a fleischer kasooda then there are more eggs but if you mamash have no other knife and you made me eat so we'll soon see that means you stuck the knife into the ground 10 times we'll soon discuss that then you could cut use the knife of the other men what is ramos saying there is ramos saying that in order to use a milky knife you have to make the iza before you cut kala it's not reasonable khal is powerful and the knight the milk and knife is clean he says no neitze is only needed if you want to cut cheese la marshall with a fleischick knife then you have to be very careful you have to make me eat it 10 times to make sure it's clean but if you want to cut halo with a milky knife as long as it's clean it's good enough but say what he says is not true the mashal says even if you want to cut innocent challenge with the milk it's not enough that it's perfectly clean you have to make naitsa a himalayan if you're cutting with a clean melaka knife powder color but it might become flashes but the shock says but but i don't agree but at least has to be clean in other words to use a milk a knife on par of a place you can see there's a problem now the taj is a little more mako and he says you don't need the it'sa and akharaf needs me it'sa our case as long as the military knife is cleaned properly there's no mamashes if there's no manmashes what's your problem strongly disagrees with the task so you can't use a milky knife to cut kala for fleshy kasuda imagine it shouldn't be according to my shot you have to have an ita but basically the point that it has to be scrubbed well now this is a clean nightmare the point is because as we saw and we will see the most problems in the initial kitchen comes out of a wrong knife a place sugar knife cuts an onion and you put it into a milky soup it's it comes straight a flake shake a clean knife a tray for knife cuts a a a piece of a horseradish it's strafe kool-aid you know this is the point that we have to hear most important you know per hashem the national countries have humans sometimes that defy explanation but you have to go along with the vision values when it comes to a knife it's not hummus it's venom i told you earlier with the with the knife even if it's clean the shack says even though i'm makel but only be the ever don't use a milky knife even though he's makeup there are more said he's both in the end of pay test supposed to have two separate knives play sticks and military and don't mix the two today you need three different knives miller x flagships and power and your boys i'm telling you from experience most childhoods come because people are not faithful to these three knives cutting a carrot what's the cutting onion what's the big deal so i used a milk into the power of a knife you put it into a flashing roast you could have busted could be their iso so i it's strongly advised having three you know different knives different labels discernible not looking the same and it could die to buy three parabolics i'll explain you why one gets lost the second one is left in the cake put in the freezer you can't find it and the third one hopefully you'll find it and if not you'll say um but if you have three you might find one if you have one there's no chance so it's good for the shambhala it's also good for the the castris but la maison never used the opposite knife drama says it you know with the knife only in the easter is not to that the point is knives are the greatest problems in the yiddish home people in the mountains they they don't want to step up too many knives they have one sharp knife they use it for everything sharp knife it has more more duchene and that's not right even the shackle said it's not right this of course i should say it to use a flagship spoon to scoop out cottage is also wrong even if it's clean because you don't mix meaning but with a knife the problems are much more severe consider the next question a person cut a carrot with a let's say with a military knife okay can he put it into a fleishiga dish so first wait a minute was it a clean knife perfectly clean he even made the it's a perfectly knife but he wants to put into a flame shaker dish milky and i've cut the carrot we'll say what's the problem oh there's no sham nunes it's a clean eye there's no horror if it's a carrot there's no heat when you cut it true the only thing is does make a problem independently don't forget he cut the carrot with a milky knife does conduct alone cause some transfer from the milky knife to make the carrot milks so the answer is basically most points say no because dukkha does not create problems it is a problem it could connect to but if there's no nothing to worry about there's no mamashes it's not kharif so basically the carrot remains strictly powerful now of course the if it had been a har if you have a problem but it's not a harvest and the you could even put this into play sticks the boys can say don't do that because we don't even cut khala with the military knife these are foreign so it's not ideal but the dukkha factor alone is not an operation in this situation so again we don't put a hat killer with a milky carrot to cut a middle of the knife to cut a carrot to put into chicken soup but beat the evidence if it was done your only cheese him the carrot is basically powerful it's like the luxian that's basically powerful but don't mix with the other men now let me ask you the next question and that's a little more tricky but but i said we have to really understand what allah is if let's say a person cut cold meat with a milk a knife that was sparkling clean no mamas whatsoever he made it no mom washes so he cut a cold piece of meat with a milk clean milk a knife so the knife needs a thicken i wouldn't say yeshua needs a chicken because it has a smearing of a meat or you cut meat it left some nunes so forget about tonight tonight needs a cleaning a good cleaning what's the locker with the meat so you're wondering that's the previous case how could how could the meat be affected he said is ineffective to make a problem and taka there are poison that say that it's no problem the meat believe it or not is perfectly okay don't do it of course but it's okay but here we come to another unique feature of the knife or particularly that this case the meat is affected i why is it different in the previous case so it's very simple when you cut the meat with a milk a knife the little bit of the milk cablius goes straight into the meat i had to go straight into the meat of akina makes a little connection enough to make the meat connect to the bliss of the color i the previous case of the carrot i have no problem if a little bit of the milk knife goes into the carrot what's a little bit of milk is in a carrot nothing it's not been at the term but here the little bit of the milk knife goes into the meat and a little bit the layer outside layer it has a slight of affection and infection i should say of the bacchalav in other words akina makes a little bit of a connection so if you have from from milkies into carrot okay but here it's going into meat and it's almost like sleep of not by not straight in is a problem and that is so if you realize your mistake before you made any further work with the roast cut off the outer layer or perhaps they place it even rinsing would be enough because it was again a very mild infection but the myself if you took the roast and put it in as it is and you you didn't treat it you could assume like otherwise can say that this this situation the duck is not enough to make a problem because everything is cold and it's not a curve but again you see that the potentially duck alone could make a transfer from a clean knife into a cold piece of meat and that's obviously something to be concerned about now a person had to shy he cut up some cold cuts small pieces and put it into a salad of course if it's a salad and then they use a milk a knife so here we'll say if the knife was clean so we were lying the sheet is there's no transfer the the cold cuts are not affected let's say he's afraid that the knife the milky knife had a little bit mamashes on it so then you have to make a husband is there enough salad and the meat to be mavato a little bit of my monsters if it's only a sophomore mushroom a little bit of mamas you could hopefully could assume hopefully they might be shishin now the same is true a clean flay sugar knife this is an arab pastel arab shabbos arab shuis scenario a clean flay sugar knife cut cheesecake or any cheese cold cheese dish so if the knife is clean so past this there's no transfer say if a trimmer says a little bit transfer you have to take off the outer layer if the knife had mamashes of flay chicks and you cut cheesecake do you have a problem not the whole cheesecake it didn't spread the whole cheesecake the place that you cut on both ends where you cut scrape off the outer layer and you have no problems with the rest of it there's no transfer more than just putting a little bit flake sticks onto your cheesecake so basically it's the same you say just realizing what the story was i should mention if someone cut you to use a flayshicken knife to cut a soft uh creamy cheesecake that's made out of let's say a very soft cheese it could be no duck with the sake in that case i said you cut something that's firm or semi-firm meat cheese american cheese but if it's a very soft cheese even like to say if i trim us the cheese remains unaffected the next group of questions really are probably the most challenging and that is a person cut hot foods with the wrong knife so let's start with an easier side hot google a hot cake came out of the oven and someone was very making it on tayameha a little bit two macbooks using magademia took the first knife picked up the knife and cut off a piece of potato cooker or a cake and he realized that he cut the kugel luck cake with a flake chicken knife and he wants to have an early time there and wants to have a coffee milk can you have miller hicks with a power of a kuggle or cake that was cut with a flai chicken knife so if the night the frey chicken knife had mamashes so what's the shyla you can't drink milk with a little bit fly sticks but let's assume that the knife was clean but it was a benjamin of fleischick's so this the piece can say ideally you shouldn't have with milks because just like if you cooked powerful action in a fleishiga pot you don't add the cheese to the powerful oxygen because you're mixing too many so here the milk the place you can knife cut the kugel or the uh cake ben you might heat the heat of the cooking of the cake made a transfer so you have a knot from the knife place your knife going into the power of a cake or coogle that's like power of election that you don't have it together with the other men so obviously that's why power of a knife to the rescue if you had a power of a knife handy that you could find you would cut the coogle or the cake or the whatever it is with the power of a knife and you don't go wrong if you cut that cake or kogel with a milk knife it's not possible to have the coogle with the flesh you can soothe them because the same thing now the kuggle is like the powerful locks you don't have with the other men so that's why mustang mustang slow down first of all and number two have the parabon knives available that would have remedied or prevented this problem the knife in all cases is unaffected you cut a milk a knife and powerful food the knife's not a problem the problem is the food what's much more serious and that is when you cut a rose the hot rose with a milk a knife so of course the rub has to find out what type of milky knife was it or not so let's go slow push it no doubt about it if you person cut a small piece of meat not a roast small slice of meat with a milk a knife even if the knife was perfectly clean no my mushes but it was a military knife benjamin the bossa is also probably us all right what's the problem well i'll tell you the problem hot piece of meat heat a milky knife that the benjamin believes the miller fix so the heat with a dukkha makes a transfer the only issue is if that's considered is that derek bishop told us if sli is boss behold their eyes are all different but it's quite possible to say that this slice of meat is based it's going into the meat and and there's no shisha that's why i chose a small piece of meat now of course i want to make a point again to the rest of the sugiya question from the end of our semen and i'm sorry in cement hey that when the rav has a child with a melaka knife let him first ask uh rabbit is it really a military knife now write something has to be studied properly he says because typically in our times he writes we don't have middle knives we have butter knives or a cheese knife that just smeared you know butter but not it's not hot believe in a military knife now this time that was probably true but today we have dozens of hot milky foods i mean they didn't have those things and lasagna and pizza and and all these other foods eliminate them and blintzes and gin and cheese cookers and bacon parmesan loads of hot foods so it's certainly possible that a knife is really mild gablius benjamin so that's why this cut rock this cold cut piece of meat there's no shishan if you're talking that the meat is also bus because of the horizon here you have you have the allocation it's a benjamin and it is also and is the heat of the piece of meat that's the higher posit without my moshes and koshking with my mushes the question is we cut up a roast an air smu is not a time to eat the roast is awesome but you can't be mocked there what's awesome but let's work slowly first question is is the knife in any benue don't forget if the knife was not used within 24 hours then the miller hicks are discounted and the rose remains perfectly mutable the knife has to be cautious but the rose is okay recommends is it really a knife that was used for military hot milk for 24 hours if it's not then you're fine if lameisom he did it right so to speak and everything was a problem it's a benioimide and it's a miranda knife he has a problem let's say he says it wasn't an eben but i it was the knife was used pretty recently like today whatever but i have my mushes on it i give up my mushes even ain't benji is a problem but it's not the end of the world you cut the roast in half let's say so on both ends scrape off a little bit that that was affected and the rest of the rose is perfectly muted there's no transfer beyond that even though we said when you have heat it transfers but you have to realize that if it's just a question of the mammoth shiboy we could assume that that doesn't go that deep hopefully it doesn't go that deep but the problem really is let's say the knife was a benjamin ortiz that taka we have to assume that went deeper it was real my moshes so this is a problem so here i must tell you that the the next question is tell me the rose was really ya to let lettuce if the rose is not yazoo lettuce then the blue is all the moisture doesn't penetrate because once it's not too hot or it doesn't doesn't affect the the rest of the roast then all you have is the exterior then you could take then then you could take off the cadet clifford but in the case where it's a hot roast taco like i said like i said earlier it penetrates throughout the roast whether it's a a clean knife or certainly a dirty knife so the myself if you have all these combinations it's a ben yoimai it's a hot rose that's yatsu let this boy and take it it's a real milk iblis of beimei then it's quite possible the entire roast is problematic the only thing the way to say this is how much milk in the worst scenario enter this roast it's not a piece of cheese it's at most the volume of the blade of the knife not the handle just the blade even if it's full of militably is benham so you have to be able to determine if the 60 shishim of the meat connected the blade so you have to actually try to figure this out but imagine can you line up 60 blades and is that bigger than the roast i saw on a wonderful safe for safer called hilca's boston bacola very reliable safe he worked hard he did his homework and paid tough lamborghes he said that he on a standard blade you need six kaze sim of meat to movato the entire blade in other words six kisses and you could assume this can i get a standard blade not a big knife but a standard blade so that's the way of figuring it out because it's not that big the size of half an egg do you have the size of six kisses then you could say that even if the blade taka was full of milk their meat remains unaffected it's bottled but the real problem is that he did it right or did it wrong and it's a small piece of rose and there's no shish and it's a benj and it's really bliss from to come from so the only way to salvage this situation is there's one more question typically people don't cut roast in the roaster they take it out and they put it onto a cutting board inside of dalek zayin oh meat on a cutting board is already a cliche knee cliche can't cook so how could that affect how could the milky knife affect the meat if it's cliche and beyond bishop however not all agreed to this rama at all that's putting him mildly to quote the towers and many other places but this mead is not a cliche like soup that was transferred from from from from plate to plate this is a double bush a salad that retains its heat you see on the super the cliche not so hot but the tornado or the carrot is very hot why a solid food even if it's transferred retains the heat but as the poison say more so here you have a sakina in effect and the knife the milky knife even though the meats are cliche but that's important more of the military into the roast and that's why the adam and claus called seafood base insists that if there's no sheeshin even if it's a cliche that roast is us even with the avid the maison says that if targets are cliche you could be make only cliche but here you see the effect of a knife it's a clean knife no mamashes cutting a roast if there's no sheesham and if it's a cli register and all agree that the rose would be awesome even but the evidence might even be real boston now how to what doesn't it mean we spoke about it so basically there's a hyena diameter inchi if you have a tray for knife stick it in the ground 10 times and you're good to go there's no such thing some people say if you leave it 24 hours it helps no such thing you can't cash it with ground and the itza is a gemara at the very end of a desert of involvement base in yardaia kufraval of zion is in one type of scenario let me be very clear a person has a trayfa knife with bliss you can't use it but he wants to cut another knife wants to cut a cold food but this besides the bliss which is a problem these mammos how do you get it from bosch's stomp scrubbing will not get off a mush that's caked on and so much part of the knife that's when the itza works when you have a stubborn mamash is stuck on the knife just rinsing is not going to come off sticking into the ground and the way the gemara explains with twice's addition not just stick it into sand you have to get ground that's not soft not too hard it's firm enough that it takes off the abrasion takes off the mambasis ten times in ten different places not the same place eventually makes the knife clean and there's no momoshes so you can use it on hot coaster food on so on cold food when you have nothing else so in other words itsa only takes off the mamashes that's caked onto a knife but doesn't casher it can't cash them now the places say today we don't even have the ability to make the eats i mean in brooklyn where to get earth 10 flower pots i mean it'd be very creative it has to be just the right type and already the through our show right we don't use the eats of his mouth but definitely is not the mucking pasturing now when a person wants to get off a mamas on the knife today the best eights is steel wool not that steel wool isn't it because the price in the it's hazal said it's only but that's what gets off the stubborn accumulation on the knife as you want to mention the last question about the kashmir's issue so people ask they want to buy watermelon in a non-kosher supermarket now watermelon is kosher obviously but i don't know what knife they use they might have used a tray for knife so the ms if they use a tray for knife you have a problem because whether it's the even if it's uh even though watermelon is not a double carp but it's my moshes and it is my mushrooms it goes on to the watermelon you have to eat and washing won't help so some people attack them don't buy by non-kosher store or they buy and they cut off the top layer or they buy by eating and kind of mix with their eyes are kind of out of me if you ask it's hard to believe in a big establishment they're going to use the knife that they use to cut their tray for sandwich for lunch they're gonna cut the watermelon there's a special hatchet you know it's pretty big they can't use a small knife and they don't use the hatchet to cut the little sandwich so hopefully you could assume that they don't use a tray for knife on the watermelon especially when you buy watermelon you taste flake chicken you know you're not going to buy again so the way mario nasty i can't say it's perfectly right but if that it's definitely not us watermelon that's cut in a reliable store you could assume it's okay the last question is fish that you buy in a fish store some some out of town community don't have a kosher fish store so fish obviously is cold but the problem is that in a non-kosher fish store they have non-kosher fish and the the knife is allowed to use from fish to fish they don't know you're a hit so the best date is come in respectfully with your own knife and say i'd like to buy this you see the these the scales and the fins and let them cut with your knife of course you're safe if you buy a piece of fish and you know it's a kosher fish it has a simone but maybe they use it before to cut a shark or tray for fish you can't tell and there's nothing illegal nothing like maraude would using a knife they'll just cut a tray for fish to cut your fish so then hopefully hopefully rinsing off will do the trick some say you have to scrape it off so the javascript is a syrup if you take a knife and you basically go over the very firmly that might take up any my muscles and the fish considered kosher i couldn't talk to you all right that's right shameless i would like to thank robert smith for the wonderful shirt i've always said this shop is this message researcher to make a special appeal it's not called appeal it's a partnership everybody knows about adapter coil our bismarck reserved to adapt a special coil and a straw with many many like real strong kamida khamenei
