Of this genre, the most popular is undoubtedly the traditional pineapple upside-down cake. Any fruit can be used, however, and this dessert is made by covering the bottom of a cake pan with butter and sugar topped with decoratively arranged fruit, then cake batter. During the baking process, the sugar, butter and fruit juices combine to create a caramelized glaze. Before serving, the cake is inverted onto a serving plate so the glazed fruit becomes the top of the cake.
