This is a deliciously moist and dense bread, full of nuts and fruit, that keeps very well. Kletzenbrot is traditionally baked on St. Thomas Day (December 21). Then it is wrapped and stored in the fridge until Christmas Eve. The story goes, if you cut into the bread before Christmas, you will grow donkey's ears! 'Kletzen' are sweet, dried pears. Cooking time includes a one and a half hour rising time for the bread.
