What temp and how long to bake blackberry pie crust?

To bake a flaky, golden brown pie crust for a blackberry pie, follow this recipe:

Ingredients:

- 1 cup (142g) all-purpose flour

- 1/2 teaspoon sugar

- 1/2 teaspoon salt

- 1/2 cup (113g) unsalted butter, chilled and cut into small pieces

- 1/4 cup (59ml) ice water, plus more if needed

Instructions:

Step 1: Prepare the Dough

1. In a large bowl, whisk together the flour, sugar, and salt until combined.

2. Add the chilled butter pieces to the bowl and work them into the flour mixture using your fingertips or a pastry cutter. Continue until the mixture resembles coarse crumbs, with pea-sized pieces of butter still visible.

Step 2: Add Water and Form Dough

1. Add 1 tablespoon of ice water at a time to the bowl, tossing with a fork after each addition. Stop when the dough just starts to come together and can be formed into a ball. Avoid overworking the dough.

2. If the dough is too dry and doesn't hold together, add a bit more ice water, one teaspoon at a time.

Step 3: Chill the Dough

1. Flatten the dough into a disk, wrap it in plastic wrap, and refrigerate for at least 1 hour.

2. While the dough is chilling, you can prepare your blackberry filling.

Step 4: Roll Out and Bake Crust

1. Preheat the oven to 425°F (220°C).

2. On a lightly floured surface, roll out the chilled dough into a 12-inch (30 cm) circle, about 1/8-inch (3mm) thick.

3. Fold the dough in half, then in half again, to create a triangle. This will help to make it easier to transfer the dough to the pie plate.

4. Unfold the dough and gently place it into a 9-inch (23 cm) pie plate. Trim the edges, leaving about 1-inch (2.5 cm) overhang.

5. Tuck the overhang under itself to create a double-thick edge. Crimp the edges decoratively with your fingers or a fork.

6. Line the crust with parchment paper and fill with pie weights or dried beans. This will help prevent the crust from shrinking and bubbling while baking.

7. Bake the crust in the preheated oven for 20-25 minutes, or until the edges are golden brown and the bottom is set.

8. Remove the pie weights and parchment paper and continue baking for an additional 5-7 minutes until the crust is completely baked.

9. Remove from the oven and let cool completely before filling with your blackberry filling and topping.
