Panettone (also called pan dulce) is a holiday fruitcake, Italian in origin, that is enjoyed and often gifted at Christmas in Latin America. Panettone is a yeast-risen cake, similar to brioche, and it's light and less dense than other kinds of fruitcakes. It's typically prepared with a flavoring called fiori de sicilia, which gives it a strong vanilla, citrus, almost perfume-like taste.
Panettone is so popular that people often receive more than they can eat during the holidays, but like most fruitcake, panettone keeps well. This elegant English trifle is one way to use up leftover panettone. The cake is soaked in a rum syrup, then layered with rum custard and fruit, and topped off with whipped cream and more fruit.
