Lowering a gas burner on Yom Tov

Hi,

One may lower a gas flame on Yom Tov in order to cook on it, where it is so strong that it would burn food placed on it, and no appropriate flame is available.

Even if one does have the theoretical option of lighting another burner (from a gas pilot), one need not do so - it is fine to lower the existing flame.

One may not lower a flame on Yom Tov just to save gas, though.

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 1:115)

Have a great day,
Mordechai

Cooking on Yom Tov for after Yom Tov

Hi,

We have begun to discuss Eruv Tavshilin.

We have said that one may not cook on Yom Tov for another day, even if that other day is Shabbat. However, one who cooks permissbly on Yom Tov for Yom Tov itself, and produces leftovers, may use those leftovers for other days, Shabbat or otherwise.

(Shulchan Aruch Orach Chaim 527:1)

Have a great day,
Mordechai
