Shortbread 1/2 cup cornstarch 1/2 cup icing sugar 1 cup of butter or margerine, softened 1 cup flour Preheat oven to 300 degrees F. Mix all the ingredients together by hand, very gently. Make the dough into balls, using 1 Tablespoon of the dough. Place them about 2 inches apart on an ungreased baking sheet. Be careful to avoid working the dough too much - and if it begins to get too soft, refrigerate for a little while. Press the balls with a wet fork to flatten slightly. Bake about 20 minutes - do not let the cookies turn brown. Cool in pan before removing.
