Cooking on Yom Tov

From Halachipedia

General

  1. It’s permissible to cook on Yom Tov only if one intends to eat the food that’s prepared that day of Yom Tov. However, one may not cook for the next day whether it’s a weekday, Yom Tov, or Shabbat. [1]
  2. Food which wouldn’t have deteriorated by being cooked before Yom Tov should be cooked before Yom Tov. However, if one forgot, one may cook on Yom Tov but should do so with a variation from the regular method. [2] Additionally, if it was physically impossible to cook before Yom Tov, or guests came on Yom Tov one may cook without a variation. [3] Nonetheless, water may be heated up on Yom Tov even without a variation. [4]
  3. One may cook a whole pot of meat even if one only needs one piece because the extra meat improves the taste of the whole dish [5] as long as one doesn't say that one is doing for after Shabbat. [6]

Lighting the fire

  1. It’s permissible to cook on Yom Tov as long as the flame was lit before Yom Tov or the timer was set for it to begin operating on Yom Tov. [7]
  2. One may not raise or lower the temperature of an electric stove. [8]
  3. On Yom Tov, an oven which is thermostatically controlled, is permitted to be opened and closed in order to put in, check, or remove food. [9]
