Because of their frantic and hasty departure, the Jews could not take the time to let their breads rise before baking. As a result, during this eight-day holiday—also known as the Feast of Unleavened Bread—there are strict prohibitions against foods with leavening or yeast. That restriction normally leads to a seder dinner featuring traditional dishes like matzo ball soup, gefilte fish, and brisket. In place of bread, matzo, an unleavened cracker-like food, is permitted. Other baked foods, also unleavened, are made with the flour and meal from ground matzo.
Chametz (Hebrew: חָמֵץ‎) (also Chometz or Chumetz) refers to bread, grains and leavened products that are not consumed on the Jewish holiday of Passover, as well as all food items that are not specifically marked “kosher for Passover.” According to Jewish law, Jews may not own, eat or benefit from chametz during Passover.
A couple of weeks before Passover, you take a look at your kitchen and get ready for the Big Passover clean up. It’s more than the regular spring clean-up. It’s time to put away all tools of your trade and passion – the tools of traditional baking. Passover is the eight day Jewish holiday that recalls the Jewish escape from slavery. Observant Jewish homes abstain from regular baking and bakery products during the holiday, switching gears, as well as menus, to accommodate Passover traditions. In cleaning for Passover, we are first and foremost fulfilling the mitzvah of biur chametz — getting rid of chametz, it’s can actually be easy, there’s lots of room for creativity, and it’s fun.
BUT, if your are too busy with classes, too exhausted or have too many roommates to keep your house clean and kosher during the Hag, here is the tip – you can SELL YOUR CHAMETZ right here on the web site:

The prevailing custom is not to sell real edible chametz like bread, crackers, etc. The exception is when getting rid of it will involve a hardship — i.e. you’ve got a large quantity of it, it’s difficult to obtain, or it’s expensive. Yep, that easy, just click on the button and follow the instructions!
This has to be done by April 8, 2009 at the designated time for your area which will be listed on the link. (to be safe, I would do it tonight!)
Happy Holiday!
