Instructions:

1. Preheat your oven to 375°F (190°C).

2. In a large bowl, combine the blueberries, sugar, cornstarch, lemon juice, and salt. Toss gently until the blueberries are evenly coated.

3. Roll out one half of the dough on a lightly floured surface into a circle about 1/8-inch thick. Transfer it to a 9-inch pie dish by rolling the dough around your rolling pin and then unrolling it over the dish. Trim the edges, leaving about 1 inch of overhang.

4. Fill the pie crust with the blueberry mixture and dot the top with the pieces of butter.
