Preparation

• Put 1/3 cup of the confectioners’ sugar in a small bowl. In a large bowl, combine the remaining sugar with the rest of the ingredients. Refrigerate until firm, at least 1 hour.
• Scoop the mixture by the rounded teaspoonful, then roll into 1-inch balls with your hands. Put on a rimmed baking sheet, cover with plastic wrap, and refrigerate for at least 12 hours and up to 2 weeks. Just before packing, roll the balls in the reserved confectioners’ sugar, coating them evenly.
