What's an Eruv Tavshilin?

Hi,

This year, Shavuot is Friday and Shabbat. Any time there is a Yom Tov on Friday, we enter an "Eruv Tavshilin" situation.

To introduce the topic: One may not cook on Yom Tov in preparation for Shabbat. However, one may cook on Yom Tov for Shabbat, if one began those Shabbat preparations before Yom Tov started.

Preparing an "Eruv Tavshilin" - literally, "mixture of cooked foods" - means that one sets aside a baked food and a cooked food, before Yom Tov, for Shabbat. There is a specific declaration to be recited, designating these foods for this purpose - see the Artscroll Siddur, pg. 654.

Gd-willing, we'll discuss this more in the coming days.

Have a great day,
Mordechai
