To prepare crust: In a bowl, mix nuts. Add sugar and butter; mix well. Press mixture into bottom and up sides of a 10-inch (25-cm) glass pie plate. Bake at 350˚F (180˚C) until lightly browned, about 15 minutes. Set on a rack to cool.
To prepare filling: In the top of a double boiler, over hot but not boiling water, melt chocolate. Add butter and, when melted, stir to blend thoroughly with chocolate. Remove from heat. Stir in egg yolks, vanilla and instant coffee. Add brandy, stirring until blended. Fold in whipped cream and stiffly beaten egg whites. Pour filling into nut crust and refrigerate overnight or at least 8 hours before serving.
Makes 8 servings.
