The traditional Communion wafer, which we break apart and share across the table, wishing everyone the best for the following year.
According to the Polish Christmas site: The sacred white wafers, much like those used for Holy Communion, are shared with each person present. During the exchange, good wishes are expressed. This is the most emotional time of the holiday for the Polish family. Those who are no longer alive are particularly remembered at this moment. The pink wafer is shared with the animals who, according to Polish tradition, because they were first to greet the Baby Jesus speak at midnight.
