The Christmas Eve dinner known as the Feast of Seven Fishes, while surely of Sicilian origin, is a custom more popular in the United States than in Naples/Sicily. However, the tradition of serving fish on Christmas Eve is very popular in Southern Italy, where fasting on Christmas Eve is a widely observed custom. Varying widely from village to village, Christmas Eve and Christmas Day feasts are nevertheless a common tradition in all of Italy. The main meal usually occurs on Christmas Day and features roasted meat, antipasti, pasta and sparkling wine. Italy is the birthplace of panettone, a leavened sweet bread dotted with raisins and flavored with lemon and orange zest, which is cut into slices and sometimes served with zabaglione or a sweet cream made from mascarpone and dried fruit.
