Grandma Brown's Scottish Shortbread
Tastes like Lorna Doone's

3/4 c. butter (do not use margarine)
4 c. flour, sifted
1 c. sugar
1/4 tsp. salt

Blend salt into flour. In a large mixing bowl, cream together butter and
sugar. Gradually stir in flour until you have a stiff dough. Pat out onto
a greased 6X9 inch baking pan, pressing with a glass to smooth the dough.
Prick all over with a fork. Bake at 275F for 50-60 minutes or until lightly
browned.
