3/4 cup sugar
2 Tablespoons cornstarch
1/2 teaspoon ground cinnamon
1/2 cup water
3 cup blueberries
1 Tablespoon fresh lemon juice
Preheat to 475.
Combine sugar, cornstarch, cinnamon, and water. Add to a saucepan and heat rapidly until thickened. Set aside to cool. Once cooled, add the berries and lemon juice.
Pour filling into the dough lined pan. Cover with top crust, cut vents. Sprinkle with sugar.
Place pie on a baking sheet, bake for 20 minutes.
Reduce heat to 350 and back for 20-25 minutes more.
*After the first 20 minutes, I covered the outer crust to avoid burning.
