Sweetened fresh blueberries flavored with cinnamon and lemon juice and thickened with instant tapioca are baked together in this luscious double-crust pie.
This frozen dessert requires no ice-cream maker--just freeze the mixture in a pan, and scrape with a fork. If you'd like to spruce up the granita, top with chopped or halved fresh strawberries and grated lemon zest.
