2 c. butter or margarine
1 egg
1 c. sugar
4 c. sifted flour
Cream butter. Add egg and sugar. Add sifted flour a little at a time. Don't squeeze. Work like pie dough, or on slow with mixer. Chill. Mold into square roll. Slice 1/4" thick. Bake on ungreased pan. These spread very little, may be put close together.
Bake at 375 deg about 15 minutes, or at 400 deg. about 10-12 minutes. Do not brown. Bake just until very pale tan.
