Rosh Yeshiva Responds
Rabbi Linzer answers halakhic questions from rabbis and community members
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)
The Rav Moshe below rules that one could not wrap something in foil and place it on top of pot (or hot plate or blech for that matter) because of hatmanah. Is this how we pasken? Thank you.
That is not how we rule. First, if the aluminum foil is only to prevent the pot from getting dirty, and not to keep the heat, then it is not a problem. See Shulchan
