Chop candied lemon peel and candied orange peel. Coarsely grate chocolate. Mix candied lemon peel and candied orange peel, up to 1 tablespoon each, almonds, up to 2 tablespoons each, nuts and chocolate grater. Stir in flour, cocoa and spices. Slowly heat the sugar and honey in a saucepan until the sugar has dissolved and bring to the boil once.
