Permissible ways to heat up food on Shabbat: Difference between revisions

# After the fact if someone reheated food on Shabbat in an oven, if the knobs are covered you can eat the food since there is an opinion who would permit it and if not then you should wait until the food cools down so as not to benefit from the violation of hachzara.<ref>[https://www.yutorah.org/sidebar/lecture.cfm/748376/rabbi-aryeh-lebowitz/ten-minute-halacha-eating-food-warmed-in-an-oven-on-shabbos/ Rav Aryeh Lebowitz]</ref>

# In order to return food to a crockpot or the crockpot insert back into the electric setting the conditions of insulating (hatmana) and returning (hachzara) must be met (as described above). 1) If the insert pot is raised such as with marbles or the like then there's no issue of hatmana.<ref>Rabbi Willig in The Laws of Cooking and Warming Food on Shabbat p. 126 quoting Rav Elyashiv. See Orchot Shabbat p. 540 who has a letter from Rav Shlomo Zalman Auerbach who forbade doing hachzara on a regular crock-pot.</ref> 2) The food must be cooked. 3) The heating element must be covered such as by covering the surface with aluminum foil which then extends upwards and is seen before the adjustable setting.<ref>Rabbi Willig in The Laws of Cooking and Warming Food on Shabbat p. 124. 39 Melachos v. 2 p. 614 and 647 writes that in order to avoid hachzara it is necessary to line the inside with foil in order to return the ceramic pot to the crock pot heataing element. With respect to hatmana, he cites a dispute between Rav Shlomo Zalman Auerbach and Rav Moshe Feinstein. TO avoid that question he says that it is proper to line the walls of the crock pot so that they are visible from the outside. </ref> 4) At the time it was removed one's intent was to return it. 5) The pot remained in one's hands. 6) The food remains slightly warm. If it is a liquid, according to Sephardim it must be Yad Soledet Bo.
