I always make these around the holidays and everyone loves them, especially my co-workers! They look forward to them every year. They're rich, decadent, and delightfully simple to make. The only time consuming part is rolling the balls. They are worth it though!
In a double boiler, break up the chocolate squares. To the melting chocolate, add the pieces of unsalted butter, stirring often, until well blended with the chocolate. Add the coffee and rum, stirring well. Remove from heat when thoroughly mixed and add the ground gingersnaps. Mix well. Cover and chill until firm. About an hour and a half or so.
In a small processor, (or finely chop by hand), process the pecans into tiny pieces suitable for rolling. You can also use powdered sugar, or toasted sweetened flaked coconut, or walnuts. Spread the nuts, sugar, etc. on a piece of foil or wax paper.
Bring the chocolate mixture to room temperature, about 30-45 minutes to be able to handle the chocolate easily. Use a teaspoon to dig out the chocolate and form into 1" balls. Roll the balls in the chopped nuts or your choice of coconut or powdered sugar. I have tripled the basic recipe, which yields approx. 30 candies. The tripled recipe yields approximately 85-90 candies, depending on the size. Enjoy! (Most of the prep time includes chilling, bringing to room temperature, and rolling the candies).
