Entered for safe-keeping for ZWT5. From ElBoricua.com, Puerto Rican cooking site. Edited 12/16/13: The El Boricua website now lists the ingredients as: 1 box vanilla wafers, crushed; 3 Tbsp. cocoa; 1 1/2 cups finely chopped walnuts, 4 1/2 Tbsp. corn syrup, 1/3 cup rum, and 1 cup confectioners sugar (plus more for rolling balls). (It states that finely chopped coconut may also be added.) Current recipe says it makes 50-60 balls.
