Procedure
The afikoman is prepared during the fourth part of the Seder, Yachatz. During this ritual, the leader of the Seder takes the middle piece of matzo out from the stack of three whole matzot on the Seder table. He breaks the matzo in two, returning the smaller piece to the stack and putting aside the larger piece to be eaten later during Tzafun ("Hidden", the twelfth part of the Seder, which immediately follows the main meal). This is the afikoman, which is wrapped in a napkin before being hidden.
