Shabbat 18a and Shabbat 18b, working off the Mishnah on 17b about actions Beit Shammai thought were a problem even Friday afternoon, partially because Beit Shammai think we’re obligated in shevitat kelim, even our inanimate appliances should not be performing melakhah on Shabbat. Along the way, we discuss some basics of lisha, kneading, and touch on cooking topics, including shema yehateh be-gehalim, the worry lest the person will forget and stoke the coals under something continuing to be heated on Shabbat.
