Stollen is a German specialty that’s related to panettone, fruitcake, King cake, babka, and dreikonigsbrot. All these cakes were developed in medieval times and were reserved for the holidays because they were expensive to make. The most common and most famous stollen are from Dresden, Germany. It is a yeast bread made with nuts, raisins, currants, candied orange and lemon peel, and lots of butter. Some people choose to soak the dried fruit in brandy or rum before adding it to the dough, but that’s entirely optional.
