Jewish Festivals: Cooking from an Existing Flame

You may cook food on all Jewish festivals (except Yom Kippur or when they coincide with Shabbat) as long as the fire, oven, or other cooking appliance:
  • Has been on since before the Jewish festival began, OR
  • Is lit during the Jewish festival from an existing flame, such as from a pilot light or yahrzeit candle lit before the Jewish festival began.
