Sous Vide—Tevilat Keilim and Warming Food on Shabbat

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

QUESTION
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?

ANSWER

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)

2.

Walking a Dog on Shabbat

October 25th, 2020|Orach Chayim, Prohibitions|

QUESTION

Brooklyn, NY

A number of questions, regarding dog ownership and Shabbat (as well as no eiruv), and the need for dog to relieve itself on walks, outside the apartment. My apologies if this is too many questions. Any that the Rosh Yeshiva can answer are much appreciated!

1. Elevator for dog. I live on the seventh floor of building, perfectly fine for a human to walk, but dog can’t handle all those stairs. Can one rely on asking the doorman to call elevator for myself and dog?
