Study Guide Shabbat 37 This week's shiurim are sponsored by Talia Kaplan Rubin in honor of her husband, Benjamin Rubin, who has been learning the daf. She's very proud of you - keep up the good work! Today's shiur is sponsored by Tracee Rosen in honor of all her friends and colleagues who are studying daf yomi this cycle and by Betsy Mehlman for a refuah shleima for Sarah Sally bat Carrie, mother of Shoshana Nissan. The gemara tries to find an asnswer to the question - is the beginning of our mishna talking about leaving an item on the flame from before Shabbat or retunring something to the fire on Shabbat? Does the mishna ohld like Chananiya or not? Is one allowed to put a pot next to the fire to warm up even the coals are not swpet to the side or covered up with ashes? The gemara brings the opinion of Rabbi Oshaya and three versions of Rabbi Yochanan regarding the issue of putting something on the fire before Shabbat - do the ashes need to be swept to the side or covered? Does it matter if the food is fully cooked or is it sufficient if it is partially cooked (maachal ben drosai)? Does it matter if the food will be imporved with more cooking or is it only allowed if it will get worse if one cooks it too long? The gemara then brings different opinions that were practiced in different places.
