Borracho is a very simple dessert to prepare. It can be prepared with various bases: pound cake, vanilla cake, sponge cake, or ladyfingers. Just prepare the syrup, sauce and assemble it.
In a small pot mix the sugar and ¾cup of water, and bring to a boil. Remove from the heat and let cool for 10 minutes. Add the rum and pitted prunes and set aside. (This can be left overnight for stronger flavored prunes.)
