1/2 cup dairy sour cream
1 cup butter or margarine
1 1/2 cups flour
Fruit filling

Mix sour cream, butter and flour together. Divide dough in half, wrap and refrigerate for 8 hours. Roll dough out and cut into even squares, 4 inches or larger. Put 1 1/2 or more teaspoons of fruit filling in center of squares. Fold over into triangles and press edges before baking. Bake at 350 degrees F until light brown. Dust with confectioners' sugar if desired.
