The word “seder” comes from the Hebrew meaning order. At a seder you have a booklet called a haggadah telling the story of the Jews’ departure from Egypt. There are several ceremonial foods including matzoh, haroses (a mixture of wine, nuts, and apples), horseradish and parsley. The significance of each of these are explained in the book; such as, “this matzoh, why do we eat it?” I’ve often thought it would be great if Thanksgiving had a similar book with lines such as, “these creamed onions, why do we eat them?” or “what does this cranberry sauce mean to you?”
seder – The feast commemorating the exodus of the Jews from Egypt, celebrated on the first night or the first two nights of Passover.
