1 1/4 c. all-purpose flour
3 tbsp. cornstarch
1/4 c. sugar
1/2 c. (1/4 lb.) firm butter, cut into pieces
1 tbsp. sugar

Mix together flour, cornstarch and sugar. Rub in the butter with fingertips until crumbly and no large pieces remain. Gather mixture together into a ball, place in an ungreased 8 or 9 inch round baking pan. Press out firmly into an even layer. Make impressions with the fork around the edge and prick the surface evenly.
