what is chametz
Discuss (42). Chametz is any food product made from wheat, barley, rye, oats, spelt, or their derivatives, which has leavened (risen). Our sages have determined that flour from any of these five grains that comes in contact with water or moisture will leaven, unless fully baked within eighteen minutes.therwise it is possible that it contains chametz ingredients, or traces of chametz if it was processed on the same equipment as chametz products. Thus, unless a product is certified Kosher for Passover, we consider it chametz, and make sure not to have it in our possession on Passover.
