The holy trinity of baking spices: ginger, cassia-cinnamon and allspice combine in this traditional medieval spice blend called Poudre Douce. It makes this upside-down fruit cake an essential for the winter holidays -- and it's a table-top stunner, too! We made a festive selection of dried fruits over the classic pineapple to allow the spices to shine through. Less sweet than those pineapple upside-down cakes of our childhoods, we like this cake at brunch as well as for dessert!
