Sharing of the oplatek (pronounced opwatek) is the most ancient and beloved of all Polish Christmas traditions. Oplatek is a thin wafer made of flour and water, similar in taste to the hosts that are used for communion during Mass. The Christmas wafer is shared before Wigilia, the Christmas Eve supper. The head of the household usually starts by breaking the wafer with his wife and then continues to share it with everyone at the Wigilia table. Wishes for peace and prosperity are exchanged and even the pets and farm animals are given a piece of oplatek on Christmas Eve. Legend has it that if animals eat oplatek on Christmas Eve, they will be able to speak in human voices at midnight, but only those who are pure of spirit will be able to hear them.
This tradition dates back many centuries when a thin, flat bread called podplomyk was baked over an open flame and then shared with the family gathered around the fire on Christmas Eve. Patterns would be cut onto the bread to make breaking easier. This is why oplatki today still have patterns on them, usually of Nativity scenes.
