Ingredients:
- 2 1/2 cups (300g) all-purpose flour, plus extra for dusting
- 1 teaspoon (6g) salt
- 1 cup (227g) cold unsalted butter, cut into 1/2-inch cubes
- 1/2 cup (113g) cold sour cream
- 2-4 tablespoons (30-60ml) ice water
Instructions:
- In a food processor (or mixing bowl), pulse (or whisk) together the flour and salt.
- Add the cold, cubed butter to the flour mixture. Pulse (or use a pastry blender) until the mixture resembles coarse crumbs. The key is to keep the butter cold!
- Add the cold sour cream and pulse (or mix) until just combined.
- Gradually add ice water, 1 tablespoon at a time, pulsing (or mixing) until the dough just comes together. Be careful not to overmix.
- Divide the dough in half and form each half into a flat disk. Wrap each disk tightly in plastic wrap.
- Refrigerate the dough for at least 30 minutes, or up to 2 days. This is crucial for developing gluten relaxation.
- On a lightly floured surface, roll out one disk of dough into a 12-inch circle.
- Carefully transfer the rolled dough to a 9-inch pie plate. Trim and crimp the edges.
- If pre-baking the crust (for a custard pie, for example), prick the bottom with a fork and bake at 375°F (190°C) for 15-20 minutes, or until lightly golden brown. Consider using pie weights or dried beans to prevent the crust from puffing up.
- Fill with your desired pie filling and bake according to the filling recipe's instructions. Monitor the crust to avoid over-browning; you can use a pie shield or strips of foil to protect the edges.
