Frozen Blueberry Pie

Preheat the oven to its highest temperature setting, which is 425 degrees F (220 degrees C).

Make the filling by combining frozen blueberries, sugar, cornstarch, lemon juice, and salt in a medium-sized cooking pot. Ensure the blueberries are evenly coated with the dry ingredients, then place the pot over medium-high heat. Stir frequently to prevent burning and cook for 10 to 15 minutes, or until the mixture reaches your desired consistency.

While preparing the filling, create the crust by mixing flour and salt in a large bowl. Use two knives or a pastry blender to cut the 3/4 cup of butter into small pieces until you achieve a mixture that resembles coarse crumbs. Gradually add 1 tablespoon of water at a time, mixing well with a fork until the flour mixture is moistened. Be cautious not to add too much water, as this can lead to a sticky dough.

Divide the dough into two equal parts and shape each portion into a ball. Using one of the dough balls, roll it out with a rolling pin into a 10-inch circle. Transfer this circular shape to a 9-inch pie dish and trim the edges using scissors to create an even border. Crimp the rim of the crust by pressing your fingers and knuckles into it.

Fill the prepared pie crust with the cooked filling, leaving a small border around the edges. Dot the top of the filling with 1 tablespoon of butter.

Create a lattice crust by rolling out the second dough ball into another 10-inch circle. Use a sharp knife or pastry wheel to cut this circular shape into thin strips, approximately 1/2 inch wide. Begin by placing the longest strips in an X pattern at the center of the pie, then alternate horizontal and vertical strips to create a woven design. Use shorter strips for the edges of the lattice, folding them under the edge of the bottom crust and crimping to seal.

Combine 1 teaspoon of butter with milk in a microwave-safe container. Microwave at short intervals until the butter is fully melted, then brush this mixture over the pie.

Bake the pie in the preheated oven until it reaches a golden brown color and is bubbly, approximately 30 minutes.
