The culinary feast either takes place at supper on Christmas Eve or on the first day of Christmas. Traditions vary from region to region; carp is eaten in many parts of the country. Potato salad with frankfurter or wiener-sausages is popular in some families. Another simple meal which some families favor, especially in regions where Christmas Eve still has the character of a fast day, is vegetable or pea soup. In some regions, especially in Schleswig-Holstein where Danish influence is noticeable, a roasted duck or goose filled with plums, apples and raisins is family tradition. In other regions, especially in Mecklenburg and Pomerania, many families prefer kale with boiled potatoes, special sausages and ham. Many families have developed new traditions for themselves and eat such meals as meat fondue or raclette. Many families in all parts of Germany bake a wide variety of Christmas cookies according to recipes typical for the family and the region.
