Do we have to taste from the egg and bread after doing the blessing of Eruv Tavshilin or wait till Shabat to eat it. Thanks.
There is no need to taste the Eruv. There is a Minhag to eat the Eruv at Seuda Shlishit on Shabbat. One should make sure NOT to eat up all the Eruv before Shabbat. Rabbi Yitzchak Grinblat
