Ingredients:
- 2 ½ cups (312g) all-purpose flour, plus more for dusting
- 1 teaspoon (5g) salt
- 1 cup (227g) cold unsalted butter, cut into ½-inch cubes
- 6-8 tablespoons (90-120ml) ice water
- 6 cups (approximately 850g) fresh blueberries (or frozen, thawed and drained)
- ¾ cup (150g) granulated sugar
- ¼ cup (30g) cornstarch
- 2 tablespoons (30ml) lemon juice
- 1 teaspoon (4g) lemon zest
- ¼ teaspoon (1g) ground cinnamon
- 2 tablespoons (28g) unsalted butter, cut into small pieces
- 1 large egg, beaten
- 1 tablespoon (15ml) milk
Instructions:
- Combine flour and salt in a food processor or bowl. Add cold butter and pulse (or cut in with a pastry blender) until mixture resembles coarse crumbs. Gradually add ice water, pulsing (or mixing) until dough just comes together.
- Divide dough in half, flatten into disks, wrap in plastic wrap, and refrigerate for at least 30 minutes.
- In a large bowl, gently toss blueberries with sugar, cornstarch, lemon juice, lemon zest, and cinnamon.
- On a lightly floured surface, roll out one disk of dough into a 12-inch circle. Transfer to the pie plate, trim edges, and crimp.
- Line the crust with parchment paper and fill with pie weights or dried beans. Bake at 375°F (190°C) for 15 minutes, then remove weights and bake for another 5-10 minutes until lightly golden.
- Pour the blueberry filling into the prepared crust. Dot with butter pieces.
- Roll out the remaining dough into a 12-inch circle. Cut vents in the top crust.
- Carefully place the top crust over the filling, trim edges, and crimp to seal. Alternatively, use strips to create a lattice top.
- Brush the top crust with egg wash for a glossy finish. Sprinkle with sugar, if desired.
- Bake at 375°F (190°C) for 50-60 minutes, or until the crust is golden brown and the filling is bubbling. If the crust starts to brown too quickly, tent with foil.
- Let cool completely on a wire rack before slicing and serving. This allows the filling to set.
