Q: im eating cottage cheese right now and it said this on the package. :)
A: During Passover, Jewish law forbids the consumption or possession by Jews of all edible fermented grain products (Chametz) or related foods. Therefore, even foods and household products which meet the strict, year-round dietary regulations, and are considered Kosher, are nevertheless, often unacceptable, or require special preparation for Passover use in the Jewish home in order to be Kosher for Passover. Jewish Dietary law prohibits the consumption of various leavened grains and legumes during the 8 days of the Passover holiday. (Passover occurs in March or April.) OU Passover or OUP indicates that a product is processed under special supervision which renders it acceptable for Passover consumption.
