Torah Riddles Test #79

  1. Question: According to Rav Yaakov Emdan why can challah only be nullified if it accidentally fell into another batch of dough but not if it fell into the dough it was taken from?

Background:

A. The Torah requires one to take a piece of dough and give it to the kohen (nowadays we burn it) if an amount of dough of at least 1660-2250 grams of flour was made.

B. This dough is holy like teruma and can only be nullified 1 in hundred times the amount of dough it falls into and gets mixed up according to the Rema (Yoreh Deah 323:1).

Answer: Pischay Teshuva (2) says that according to him if the dough falls back into where it was taken all the dough becomes untithed again therefore it is not nullified but if fallen into some other dough it doesn’t affect that dough in anyway so it can be nullified.
