6cupsfresh blueberries(see note below for using frozen blueberries)
2 ½tablespoonsall-purpose flour
¼cupbrown sugar, packed
2teaspoonsvanilla extract
2teaspoonslemon juice
3tablespoonswater
3tablespoonsbutter, melted
Topping
1 ½cupsall-purpose flour
1cupgranulated sugar
¼teaspoonsalt
1 ½sticksunsalted butter, softened
Instructions
Blueberry Filling
Preheat the oven to 375°F.
Spray a 10-inch round deep baking dish (or equivalent size) with cooking spray. Evenly distribute the blueberries around the bottom of the baking dish. Mix 2 ½ tablespoons of flour and ¼ cup of brown sugar and sprinkle over the blueberries. Add the vanilla, lemon juice, and water to the melted butter and drizzle over the berries. Set the baking dish aside while you work on the topping.
Topping
In a food processor, add the flour, granulated sugar, and salt and pulse to mix. Cut the butter into chunks and place them (spread out) into the food processor. Process until the mixture forms a sticky dough. (If you do not have a food processor, work the flour and butter either by hand or with a mixer. Start by mixing the butter and sugar and then add the salt and flour.) Add the dough by spoonfuls over the blueberries in the baking dish.
Bake for 45-50 minutes or until golden brown and the crust in the center of the pie is cooked. If necessary, place a sheet of aluminum foil over the pie during the last 10-15 minutes of baking to keep it from over-browning.
Notes
Frozen Blueberries
You can use frozen blueberries for this recipe, but be aware of two things:
Frozen blueberries can take longer to cook than fresh ones. Cook the pie for 50 minutes. If the dough is not cooked at the end of the cooking time, add 5-minute increments, checking after each increment. Ensure the crust is cooked in the center of the pie. If necessary, add a sheet of aluminum foil to the top of the baking dish to prevent over-browning.
Frozen blueberries can develop tough skins. Sometimes the freezing process can make blueberry skins chewy, although it doesn't affect the flavor.
