Passover Seder Plate Items

If it's true that all good things come in threes, then matzo fits the bill. The crisp, flat bread made from plain white flour and water is served in a stack of three either on the Seder plate or next to it. It's a modern-day version of the unleavened bread eaten by the Jews when they left Egypt in a hurry with no time for the dough to rise. And the number three? That's said to represent the different castes of Jews.
