COOKIE TOPPING:

Plain or decorators sugar

Blend together walnuts, 1/2 cup sugar and 2 egg whites; set aside. Sift together flour and 3 tablespoons sugar. Cut in butter until mixture resembles coarse crumbs. Blend together egg yolks and 3 tablespoons milk. Add liquid all at once to flour mixture, stirring until flour is moistened. Add more milk if needed to make a soft dough. Turn out onto lightly floured board; divide in half.

Roll out each half 1/16 inch thick. Cut out circles with 3 inch round cutter. Drop walnut mixture in center of each circle. Fold in half; seal edges securely; shape into crescents. Place on greased cookie sheet. Brush tops with egg white, sprinkle with sugar (colored). Bake in preheated oven at 400 degrees for 12 to 15 minutes or until golden brown.
