Filbert Balls Yield: About 50 balls 3 1/2 ounces semisweet chocolate 3/4 stick (6 tablespoons) butter, softened 1 cup sifted confectioners' sugar 1 1/4 cups filberts, toasted and skinned, then ground Preheat the oven to 300 degrees F. In the top of a double boiler set over hot water melt chocolate and let it cool. In a bowl beat butter with confectioners' sugar until the mixture is fluffy. Stir in the chocolate and beat until creamy and smooth. Stir in filberts, and form the mixture into a ball. Wrap in wax paper and chill for 30 minutes. Pinch off 1 teaspoon of the mixture at a time and roll it between the palms of your hands like a ball.
