| To commemorate the unleavened bread that the Israelites ate when they left Egypt, we don't eat—or even retain in our possession—any chametz from midday of the day before Passover until the conclusion of the holiday. Chametz means leavened grain—any food or drink that contains even a trace of wheat, barley, rye, oats, spelt or their derivatives, and which wasn't guarded from leavening or fermentation. This includes bread, cake, cookies, cereal, pasta, and most alcoholic beverages. Moreover, almost any processed food or drink can be assumed to be chametz unless certified otherwise. Ridding our homes of chametz is an intensive process. It involves a full-out spring-cleaning search-and-destroy mission during the weeks before Passover, and culminates with a ceremonial search for chametz on the night before Passover, and then a burning of the chametz ceremony on the morning before the holiday. Chametz that cannot be disposed of can be sold to a non-Jew (and bought back after the holiday). For more on this topic, see Operation Zero Chametz. Click here to sell your chametz online. Matzah Art by Sefira Lightstone Instead of chametz, we eat matzah—flat unleavened bread. It is a mitzvah to partake of matzah on the two Seder nights (see below for more on this), and during the rest of the holiday it is optional. Click here for more on matzah. It is ideal to use handmade shmurah matzah, which has been zealously guarded against moisture from the moment of the harvest. You can purchase shmurah matzah here. The Seders The highlight of Passover is the Seder, observed on each of the first two nights of the holiday. The Seder is a fifteen-step family-oriented tradition and ritual-packed feast. The focal points of the Seder are: Read: How to Celebrate Passover |
