How do we “find our hands and feet in the beis midrash”?
1) We seem to poskin that yesh bishul achar bishul for food that is ma’achal ben drusai; cooking it on Shabbos would be chayav chatas (Rambam, Shulkhan Arukh 318).
2) Ashkenazim poskin like Chananya on the first Mishnah in the third perek. Sefardim don’t, but they also at least have to be able to read the Mishnah according to Chananya. According to him, the Mishnah says, “…If heated with peat or wood, you may do shehiyah (with food that is ma’achal ben drusai), even if the kirah is not garuf or katum. But, you may not do chazarah unless the kirah is garuf or katum.” The simple reading surely is that, if the kirah is garuf or katum chazarah is permitted with food that is ma’achal ben drusai.[Otherwise, the Mishnah would be changing the case in the middle.]
3) All rishonim except for Rashi seem to hold that garuf v’katum doesn’t stop the kirah from cooking, but serves as some kind of a heker or barrier, preventing the person from stirring the coals. Or, that without garuf v’katum, it “appears to be cooking” (מחזי כמבשל). But all these rishonim must hold that a kirah that is garuf v’katum is still fully capable of cooking.
So how is possible to read the Mishnah according to Chananyah?
I've been asking this question of people for years.
By the way, the same question seems to apply on the beginning of the mishnah: With קש וגבבה (straw and stubble), you may "place" food on the kirah. According to Chananya, that means doing chazarah, and with food that is מאכל בן דרוסאי, only partially cooked. How is that possible, if the straw and stubble add enough heat to cook?
