Preparation:
Place chocolate morsels in top of a double boiler; bring water to a boil. Reduce heat to low; cook until chocolate melts. Add butter and powdered sugar, stirring until sugar dissolves. Remove from heat. Add egg yolks, one at a time, beating with an electric mixer after each addition. Pour mixture into a bowl; cover and let sit 12 hours in a cool, dry place (do not refrigerate). Shape mixture into 1-inch balls; roll lightly in cocoa. |
