4 egg whites
1/2 teaspoon cream of tartar, optional
4 ounces sugar
2 tablespoons all-purpose flour
4 ounces confectioners' sugar
3 ounces nut powder, optional (Nut powder is equal volume by weight of confectioners' sugar and a roasted nut of your choice. I like hazelnuts, peanuts, or almonds).
2 ounces cocoa powder, optional
