Cape Cod Blueberry Pie Recipe

On a lightly floured surface, roll pastry dough to a 1/8-in.-thick circle; transfer to a 9-in. pie plate. Trim pastry to 1/2 in. beyond rim of plate; flute edge. Refrigerate 30 minutes. Preheat oven to 425 °. Line pastry with a double thickness of foil. Fill with pie weights, dried beans or uncooked rice. Bake on a lower oven rack 20-25 minutes or until edges are golden brown. Remove foil and weights; bake 3-6 minutes longer or until bottom is golden brown. Cool completely on a wire rack. In a small bowl, mix flour, salt and 1/3 cup water until smooth. In a large saucepan, combine sugar, 1 cup blueberries and remaining water; bring to a boil. Stir in flour mixture. Return to a boil, stirring constantly; cook and stir 4-6 minutes or until thickened. Stir in vinegar and remaining blueberries; pour into crust. Refrigerate 4 hours or until filling is set. Serve with whipped cream.
