This is my favorite recipe for blueberry pie. I will be listing it under my favorites on the blog. This pie does not last much over a day at my house.3/4 cup sour cream 3 tablespoons all-purpose flour 1 cup sugar 1 tablespoon lemon juice 1/2 teaspoon cinnamon 1/4 teaspoon salt 2 teaspoons vanilla flavoring 1 egg, beaten 2 cups fresh or frozen blueberries 1 (9 inch) unbaked pie shell (I use Pillsbury frozen pie crust) In a large bowl beat sour cream, flour, sugar, vanilla, salt, egg, lemon juice and cinnamon together with mixer. Fold in blueberries and pour into pie crust. TOPPING: 4 tablespoons butter or margarine, softened 4 tablespoons all-purpose flour 1/2 cup walnuts, chopped In a small bowl cut butter into flour. I use a fork and just kind of mash it all up together. Mix the nuts into the butter and flour. Sprinkle over the pie before baking. (See photo) Bake pie in preheated 400 degree oven for 30 to 35 minutes. Let cool. Enjoy! © The Southern Lady Cooks photos and text – All rights reserved.
