Daf 108 — Chullin 108 Summary

Chullin 108 – Good Morning Raboisai Meat and Cheese Together The Mishnah says: • Meat and cheese may be wrapped together in one cloth • Provided they do not touch each other Why? If they touch while cold: • They do not become forbidden immediately However: • Residue from one may remain on the other • One may later forget to wash it off before cooking Therefore: • They should not be allowed to touch. Two People Eating Meat and Dairy Two people may eat at the same table: • One eating meat • The other eating cheese When: • They do not know each other Reason Since they are strangers: • They will not normally take food from each other The concern is when people are comfortable: • Sharing each other's food. Two Brothers Who Are Makpid The Gemara asks: What if two brothers are: • Makpid on each other • And will not eat from each other's food? Can one eat meat and the other dairy: • At the same table? Even though they will not share food, the Gemara compares this to other Rabbinic decrees where: • Chachamim did not make exceptions based on individual circumstances The Gemara discusses examples involving: • Decorative bread • Washing one's only garment on Chol Hamoed טיפת חלב – A Drop of Milk Milk Falls onto a Piece of Meat The Mishnah: A drop of milk falls onto: • One piece of meat in a pot If enough milk is absorbed to: • Give flavor to that piece Then: • That piece becomes forbidden. However, if the pot was immediately stirred: • The milk spreads throughout the entire pot We then ask: • Does the milk give flavor to the whole pot? If not: • The mixture is permitted. Difference Without stirring: • The milk is concentrated in one piece With stirring: • The milk is distributed throughout the pot. Is Taam a Torah Principle? The Gemara discusses the principle that: • Forbidden flavor can prohibit permitted food Could we learn this principle from: • Basar b'chalav? Problem Basar b'chalav is a chiddush: • Meat by itself is permitted • Milk by itself is permitted • Yet cooking them together makes them forbidden Also: • The Torah uniquely prohibits the actual cooking of meat and milk together. Therefore: • We cannot necessarily use Basar b'chalav as the source for other prohibitions. Rava – Why Does Flavor Matter? The Gemara asks: If Basar b'chalav is such a unique chiddush: • Why should it depend on the milk giving flavor? Rava answers: • The Torah describes Basar b'chalav as bishul – cooking Cooking means: • The meat and milk affect each other through the cooking Therefore: • Taam – transferred flavor – is significant even within this unique prohibition. חתיכה עצמה נעשית נבילה Rav – The Piece Itself Becomes Neveilah Rav says: If enough milk enters a piece of meat to give it flavor: • The entire piece becomes forbidden This is the principle: • Chatichah atzmah na'asis neveilah Meaning: • The entire piece is now treated like a piece of neveilah. What Happens to the Rest of the Pot? The forbidden piece continues cooking: • With the other pieces of meat According to Rebbe Yehudah: • Min b'mino is not batel Therefore: • The forbidden meat can prohibit the other meat in the pot. If the pot also contains another type of food: • That different type can potentially be mevatel the forbidden piece The Gemara distinguishes between: • A thin mixture • A thick mixture where the contents are treated differently. אפשר לסוחטו Can the Forbidden Piece Become Permitted Again? The Gemara introduces: • Efshar l'sochto The question: If milk was absorbed into meat, but the milk can later be: • Extracted from the meat Does the piece remain forbidden? Two Views Rav, Rebbe Chanina and Rebbe Yochanan: • Efshar l'sochto → Asur Shmuel, Rebbe Shimon bar Rebbe and Reish Lakish: • Efshar l'sochto → Mutar Rav therefore holds: • Once the piece becomes forbidden, removing the absorbed milk does not make it permitted again. Meat Falls into a Pot of Milk A whole piece of meat falls into: • A large pot of milk Rav says: • The meat is forbidden The Gemara initially discusses why: • The surrounding milk might nevertheless remain permitted Question Milk entered the meat and became part of the forbidden Basar b'chalav. If that forbidden milk then comes back out: • It should mix with the rest of the milk And according to Rebbe Yehudah: • Min b'mino is not batel So why should the pot remain permitted? The Milk Can Also Become Forbidden The Gemara ultimately explains that: • The milk in the pot can indeed become forbidden However, there can be a case where: • The meat absorbs milk • But does not release it back into the pot If the piece is removed: • Before it has a chance to release the absorbed milk Then: • The remaining milk is not prohibited by what was absorbed into the meat. חצי זית בשר וחצי זית חלב Half Meat and Half Milk Rav discusses: • Half a kezayis of meat • Half a kezayis of milk Rav says: If one eats the combined amount: • He can receive malkus for eating Basar b'chalav But for cooking: • He does not receive malkus Gemara's Question Do the two halves combine or not? If they combine: • Why not receive malkus for cooking? If they do not combine: • Why receive malkus for eating? Rav – Eating vs Cooking The Gemara explains Rav: For cooking: • The required shiur of meat and milk must have been cooked together For eating: • If a proper amount of meat and milk had been cooked together • One can later eat half a kezayis of each Together: • They form a full kezayis of Basar b'chalav for eating. Levi Disagrees Levi says: • One can receive malkus for the cooking as well According to Levi: • Half a kezayis of meat • Plus half a kezayis of milk Can combine: • Even for the prohibition of cooking. Machlokes Rav: • They do not combine to create the shiur for bishul Levi: • They do combine. How Much Cooking Is Required? The Gemara concludes by asking: How much must meat and milk be cooked together to violate: • The prohibition of cooking Basar b'chalav? Answer It must reach the level of cooking: • That another person could eat it Meaning: • A genuine, meaningful act of cooking is required. Key Chazarah • Meat and cheese may be wrapped together if they do not touch. • Two strangers may eat meat and dairy at the same table because they will not share each other's food. • The Gemara discusses two brothers who are makpid on each other and whether Chachamim make an exception for them. • A drop of milk that gives flavor to one piece of meat prohibits that piece; stirring can spread the milk throughout the entire pot. • Rava explains why taam is significant in Basar b'chalav despite Basar b'chalav being a chiddush. • Rav holds chatichah atzmah na'asis neveilah – once milk prohibits a piece of meat, the entire piece becomes like neveilah. • Rav, Rebbe Chanina and Rebbe Yochanan hold efshar l'sochto is asur; Shmuel, Rebbe Shimon bar Rebbe and Reish Lakish hold it is mutar. • The Gemara discusses a piece of meat falling into milk and whether the absorbed forbidden milk returns and prohibits the rest of the pot. • Rav and Levi disagree whether half a kezayis of meat and half a kezayis of milk combine for the prohibition of cooking. • The daf concludes by defining the amount of cooking required for Basar b'chalav.
