"A Stollen is a loaf-shaped cake containing dried fruit, and covered with sugar, powdered sugar or icing sugar. The cake is usually made with chopped candied fruit and/or dried fruit, nuts and spices. Stollen is a traditional German cake, usually eaten during the Christmas season, when called Weihnachtsstollen or Christstollen. A similar cake, found in Dutch cuisine, is called a Kerststol in Dutch, while in Italian cuisine the panettone also shows a likeness." Source: Wikipedia.
It also happens to be one of my favourite type of breads/cakes. Especially when a slice is topped with real butter. Just delicious!
