Hamets vs. Chametz — What's the Difference?

Alternative spelling of chametz.

Chametz (also chometz, ḥametz, ḥameṣ, ḥameç and other spellings transliterated from Hebrew: חָמֵץ / חמץ‎; IPA: [χaˈmets]) are foods with leavening agents that are forbidden on the Jewish holiday of Passover. According to halakha, Jews may not own, eat or benefit from chametz during Passover.

Food made from grain or flour that has been mixed with water and left to sit, considered leavened according to Jewish dietary law and thus forbidden for Jews to use or possess during Passover.

(Judaism) Food products made from leavened grain flour, which may not be consumed on Passover in Judaism.
