Menachos Daf 57 מנחוס דַף 57

Rebbe Yochanan said: הניח בשר על גבי גחלים – if one placed meat onto coals on Shabbos, היפך בו חייב – then if he turned [the meat] over so the other side would roast, he is liable, but if he did not turn it over, he is exempt. The Gemara explains that the case is where, without the meat being turned, it would have cooked on one side כמאכל בן דרוסאי – like the cooking level of Ben Derosai’s food (i.e., one-third cooked), and by turning it, both sides were roasted כמאכל בן דרוסאי. Rebbe Yochanan is teaching that one-sided cooking which is only כמאכל בן דרוסאי is not considered cooking at all, and exempt. Rava adds: ואם נצלה בו כגרוגרת מצד אחד במקום אחד – if a dried-fig’s volume of meat was completely roasted on one side and in one place, he is liable without turning it over. The Gemara infers that if the roasted meat is in two or three places, they are not combined to a גרוגרת and he is exempt. In a second version, Rava says one is liable even if the roasted meat is in multiple places.

A Baraisa darshens: אשר תקריבו לה' – that you offer to Hashem, that the prohibition to prepare a minchah as חמץ applies to כשרה ולא פסולה – a valid [minchah] and not an invalid one. Rav Pappa asked: חימצה ויצאת וחזר וחימצה מהו – if one leavened [a minchah dough], and it left the עזרה, and he leavened it again, what is the halachah? Although a second leavening is normally liable, since this minchah left the עזרה before the second leavening, it became disqualified, and an invalid minchah is not liable for leavening. However, perhaps we say: כיון דחימצה – since he leavened [the dough] before it left the עזרה, disqualifying it for offering, פסול יוצא לא מהני ביה – the disqualification of having left does not affect it, and he would be liable for the second leavening. The Gemara concludes: תיקו – let it stand unresolved.

A Baraisa prohibits offering up (onto the מזבח) the meat of a chatas, asham, or any korban meat which is eaten, or the שירים of any minchah which is eaten. The passuk says כי כל שאור וכל דבש לא תקטירו ממנו אשה לה' – for any leavening or any honey you shall not burn from it as a fire-offering to Hashem, which teaches: כל שהוא ממנו לאישים – any offering from which part of it was already given to the fires of the mizbeiach, הרי הוא בבל תקטירו – is subject to the prohibition, “you shall not burn.” Amoraim discuss: המעלה מכולם על גבי הכבש – if one offers up any of [these aforementioned items] onto the ramp of the מזבח, Rebbe Yochanan says he is חייב, but Rebbe Elazar says he is פטור. Rebbe Yochanan quotes a Baraisa which darshens "ואל המזבח לא יעלו [לריח ניחוח]" – but they may not go up to the mizbeiach for a satisfying aroma to include the כבש. But Rebbe Elazar says that after the passuk mentions "שאור" – leavening and "דבש" – honey, it says "אותם" – them, teaching: אותם הוא דרבי לך כבש כמזבח – only for them did [the Torah] include the ramp like the מזבח itself in the prohibition of offering up, אבל מידי אחרינא לא – but not other items mentioned in the Baraisa.
