"Lebkuchen", or gingerbread, is a German speciality made of spiced dough which has been popular since the Middle Ages, a time when spices (cloves, cinnamon, ginger, nutmeg, vanilla etc.) were extremely valuable. The best known Lebkuchen comes from Nuremberg in Bavaria. Many families make little gingerbread houses out of Lebkuchen. These are sometimes also called "Hexenhäuschen" (or 'witches' houses') in a nod to the Brothers Grimm fairytale 'Hansel and Gretel'. These gingerbread houses are then decorated with edible figurines representing the characters in the story.
