PARSHA RIDDLE

I am challah. Hafrashas challah was not done. Today is Shabbos. If dough was kneaded in Eretz Yisroel, and one realizes on Shabbos that he did not do hafrashas challah, it's not going to be possible to eat that challah on that Shabbos. However, if the dough was kneaded in chutz laʼaretz, it's possible to eat that challah on that Shabbos (A Rav should be consulted to get instructions of what to do in such a case).
