Put 1 ¼ cups flour, ½ teaspoon salt, ½ cup butter and 2 tablespoons sour cream into a Cuisinart and blend until they form a ball. Pat out into a buttered pie tin, and bake 10 minutes at 425°. Beat 3 egg yolks slightly and combine with 1 cup sugar, 2 tablespoons flour and ⅓ cup sour cream. Pour over 3 peeled, sliced peaches arranged in the crust. Cover with foil. Reduce the oven to 350° and bake 35 minutes. Remove the foil and bake 10 minutes more, or until the filling is set.
