On Christmas Eve in Poland, families decorate their Christmas trees and put presents underneath. They prepare a traditional Christmas dinner of 12 dishes, including borsch, mushroom soup, carp, cabbage, pierogi, herring salad, and more. No meat is eaten on Christmas Eve. An extra plate is set in case of an unexpected guest. The dinner begins after the first star appears. They read from the Bible, pray, share wafer and give wishes before opening presents and singing carols. Some also attend midnight mass.
