Blueberry tart is a sweet fruity baked dessert consisting of a pie crust or a tart shell being filled with a blueberry mixture. A glaze made of flour, sugar, salt and cornstarch is poured over crushed blueberries. The filling is stuffed into the blueberry tart shells which may be baked if required. Commercially prepared or homemade make-ahead tart shells or pie crusts need no baking. Blueberry tarts may be served with cool whip.
