Open Faced Blueberry Pie

This is my favorite type of blueberry pie. It is made with a prebaked pie crust filled with fresh berries in a syrup. It is super good.
I got this recipe from one of my Rose Levy Beranbaum cookbooks. She is one of my favorite cookbook authors.

Ingredients

9 " prebaked pie crust

2 Tablespoons water
2 Tablespoons cornstarch

4 cups fresh blueberries
1/2 cup water
1/2 cup sugar
1 teaspoon lemon juice

Bake your pie crust as directed and set it to the side until ready to be filled.
Stir together 2 Tablespoons water and the cornstarch. Set aside.
Place 1 cup blueberries and 1/2 cup water in a medium saucepan, cover and bring to a boil.
Lower the heat and simmer, stirring constantly for 3-4 minutes. The blueberries will start to burst and the juices will start to thicken.
As you stir, add the cornstarch mixture, sugar, lemon juice, and salt.
Simmer for another minute until the mixture becomes translucent.
Remove from the heat and fold in the other 3 cups of blueberries.
Spoon the blueberries into the pie crust.
Let sit for 2 hours before serving so the pie will set up.
Serves 6-8.

You may keep this pie at room temperature for two days. No longer.
If you have some left after that time, store it in the fridge.
