The traditional Christmas dinner usually features either roasted turkey with stuffing (sometimes called dressing), ham, or roast beef. Potatoes, squash, roasted vegetables and cranberry sauce are served along with tonics and sherries. A variety of sweet pastry and egg nog sprinkled with cinnamon and nutmeg are served in the United States. Certain dishes such as casseroles and desserts are prepared with a family recipe (usually kept a secret). Sometimes, families also partake in a religious tradition, such as the consumption of a Christmas wafer in Christian families of European ancestry. Fruits, nuts, cheeses and chocolates are enjoyed as snacks.
