Warming Up Food on Yom Tov

May 26th, 2024|Bishul, Moadim, Orach Chayim, Pesach, Yom Tov|


Minneapolis, MN

K’vod HaRav, I’m hoping to host the second seder in shul. Our shul ovens turn off after 12 hours automatically and there is no override function. From a culinary standpoint, the best food-warming option would be to hire a non-Jewish person to (privately) turn on the ovens. Is that an acceptable approach?

The other option is for the shul to invest in some platas (hot plates) and timers, but I have found those to be very unpredictable and uneven as far as food warming goes and this seder is potentially feeding

Sous Vide—Tevilat Keilim and Warming Food on Shabbat

January 29th, 2023|Bishul, Kashrut, Orach Chayim, Shabbat, Technology, Tevilat Keilim, Yoreh De'ah|

New York

Two questions regarding a sous vide:

1) Does it require tevilah?
2) Can it be used to reheat food on Shabbat, assuming it is on and in heated water from Erev Shabbat?


1. It does not require tevilah. It does not come in direct contact with the food (plastic bag and water both intervene). (Shulchan Arukh YD 120:4, Arukh HaShulchan YD 120:32, Sefer Tevilat Keilim, 1:4 ft. 7)

Non-Jew Warming Fully Cooked, Dry food in an Oven on Shabbat For Kiddush

January 16th, 2023|Amirah LeGoy, Bishul, Kiddush, Seudah, Havdalah, Orach Chayim, Prohibitions, Shabbat|



Shalom Rav Linzer – what are your thoughts on a gentile putting dry food to warm in an oven for kiddush? I know it’s not usually done but it seems like a d’rabbanan l’tzorech rabim (rabbinic prohibition done for the sake of the community)? The venue my shul meets at (a conservative synagogue) feels that hot plates are a liability.


This is exactly the case dealt with in SA OH 253:5
