Halacha Mastery: The Kitchen on Shabbat

Halacha Mastery: The Kitchen on Shabbat

THIS IS A WEBYESHIVA.ORG HALACHA MASTERY PROGRAM COURSE. TO JOIN THE HALACHA MASTERY PROGRAM PLEASE SUBMIT AN APPLICATION. For more information about this program please CLICK HERE.

For all that it’s only one of thirty-nine, the prohibition against cooking looms larger in the Jewish experience of Shabbat than many of the others. Especially since halachah recognized that eating hot food was part of proper oneg Shabbat, the balance between enjoying the day and avoiding the prohibition created much stimulating halachic discussion. Join Rabbi Gidon Rothstein and study what qualifies as cooking, including what kinds of heat produce that cooking, when an item is considered cooked, when it cannot be cooked anymore, and then the ways Chazal tried to help us ensure that we did not slip into cooking accidentally.

Be”H, we will finish bishul achar bishul (I mean it this time!) including the question of making tea, using a dud shemesh, cooking food further once it’s fully cooked (and what that means), and an Ashkenazi cooking for a Sephardi on Shabbat, in ways permitted the Ashkenazi but prohibited the Sephardi.

Halacha Mastery: The Kitchen on Shabbat: Lesson 22
Class description

Pursuant to yesterday’s shiur, I did a quick check, and it is true that Sephardim apparently understand Shulchan Aruch Orach Chayyim 253;1 and 257;8 to mean even a covering on top of a pot  on a hot plate might be enough to be hatmanah. I’m not convinced by the reading of SA, but it’s not for me to say. (SA discusses placing the pot directly on the coals, which R. Rimon and others understand to mean even partial hatmanah is a problem as well. Except in the coals is its own problem, because I am more likely to restoke the coals since the pot is in direct contact).

I would also point out SA 257;8 allows putting blankets on a wooden panel on top of a pot, since the blankets then don’t cover the sides. Anyway, that’s the quick update.

This is the file I brought up during the course of the shiur when I realized I had left off main chazarah sources from the review sheet. It’s pp. 24-25 in the file (your welcome to look at the other sources as well, of course).
