1 cup butter;1/2 cup sugar;1 egg yolk; 2 or 2&1/2 cups flour
Cream butter and sugar then add the egg yolk. Slowly add flour stirring with wooden spoon until it is difficult to stir. Add more flour, kneading it in until dough just begins to crack at edges. Divide in half. Pat out each half into a 6 -8 inch round cake, place on ungreased cake or cookie pan. Cut into pieces but don't separate them out and then dot all over with a fork. Bake at 325 to 350F until golden on top.
