Afikomen: The Custom of the Jews of Morocco
"The Jews of Morocco eat a piece of their afikomon and save the balance. They keep this piece of matzo as a good luck charm. They are confident that, in their travels, it will protect them against all danger. If a storm develops while they are on an ocean voyage, they throw the matzo into the raging sea, claiming that it has the power to calm the angry waters."
(The Family Seder. Prepared by Rabbi Alfred J. Kolatch. Jonathan David Publishers, Inc. Middle Village, New York. 1991 by Alfred J. Kolatch)
