Pastry:
2 1/4 cups all-purpose flour
1/2 teaspoon salt
1 tablespoon granulated sugar
1/2 cup unsalted butter, cold, cut into small pieces
1/3 cup shortening
6 tablespoons ice water
Filling:
3 tablespoons all-purpose flour
1 tablespoon cornstarch
1/8 teaspoon salt
1 cup granulated sugar
1/2 teaspoon ground cinnamon
5 cups blueberries
2 tablespoons unsalted butter
Topping:
1 egg, lightly beaten
2 tablespoons milk
2 tablespoons sugar
To make the pastry, combine the flour, salt and sugar in the bowl of a food processor fitted with the metal blade. Pulse to combine, Add the butter and shortening and pulse until the mixture resembles coarse meal. Add the ice water 1 tablespoon at a time, pulsing to incorporate. Continue until dough begins to pull together. Divide the dough into 2 balls, cover with plastic wrap, and refrigerate for 30 minutes.
Just before the dough is finished chilling, preheat the oven to 350' F. To make the filling, in a large bowl, combine the flour, cornstarch, salt, sugar, lemon juice, cinnamon and blueberries. Set aside.
On a lightly floured work surface, roll out the first ball of dough to 1/8 inch thick. Place the dough in an ungreased 9-inch deep dish pie plate, allowing 1/4 inch to hang over the edge. Spoon in the fruitmixture. Cut the butter into small pieces and dot the top of the fruit mixture with it. Roll out the second ball of dough to 1/8 inch thick. Cover the pie with the top crust, crimp the edges, and pierce the top with a knife to make vent holes.
To make the topping, in a small bowl, wisk together the egg and milk. Brush the egg mixture over the top of the pie and sprinkle with the turbinado sugar. Bake in the oven for 1 hour. The juices will be bubbling through the vent and the pastry will be nicely browned. Remove from the oven and let the pie cool for 30 minutes on a wire rack before cutting into slices to serve. Pie is best served same day but can be refrigerated up to 3 days.
