Question: what is the difference between matzo and passover matzo?
Answer: Matzo that is kosher for Passover is limited in Ashkenazi tradition to plain matzo made from flour and water. The flour may be whole grain or refined grain, but must be either wheat, spelt, barley, rye, or oat. Some Sephardic communities allow matzos containing eggs and fruit juice to be used throughout the holiday.
