XXXXI: Orange-Macadamia Nut Cookies

These are also from a cooking class in high school. They wouldn't be in my files if they weren't delicious.

4 c flour
2 c powdered sugar
1 c cornstarch
2 c butter
graulated sugar
1 c chopped macadamia or walnuts
2 egg yolks
1 T orange zest
4-6 T OJ
1 recipe orange frosting (have no clue where this is)

In a large bowl, combine flour, powdered sugar and cornstarch. Using a pastry blender, cut in butter until course crumbs appear. Stir in the nuts.
In a small bowl, combine egg, 1 T orange zest and 4 T OJ. Add to flour mixture until moistened.
Knead dough into a ball. Roll into 1/4" balls.
Place on ungreased cookie sheet and flatten.
Bake in a 350* oven for 12-15 minutes.
