Ingredients:
- 2 ½ cups (320g) all-purpose flour, plus more for dusting
- 1 teaspoon (5g) salt
- 1 cup (2 sticks/226g) unsalted butter, very cold, cut into ½-inch cubes
- ½ cup (120ml) ice water
- 1 tablespoon (15ml) apple cider vinegar (optional, for extra flakiness)
- 6 cups (approximately 750g) fresh blueberries, rinsed and picked over
- ¾ cup (150g) granulated sugar
- ¼ cup (30g) cornstarch
- 1 tablespoon (15ml) lemon juice
- ½ teaspoon (2.5ml) ground cinnamon
- 2 tablespoons (30g) unsalted butter, cut into small pieces
- 1 large egg, beaten (for egg wash)
- 1 tablespoon (12g) granulated sugar (for sprinkling on top)
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 and vinegar (if using) until the dough just comes together.
- Form the dough into a disc, wrap in plastic wrap, and chill for at least 1 hour.
- In a large bowl, gently combine blueberries, sugar, cornstarch, lemon juice, and cinnamon.
- On a lightly floured surface, roll out half of the dough into a 12-inch circle.
- Carefully transfer the dough to the pie dish, trim the edges, and crimp decoratively.
- Pour the blueberry filling into the pie crust.
- Dot the filling with the butter pieces.
- Roll out the remaining dough and create a top crust (either a solid crust with slits, or a lattice crust).
- Crimp the edges of the top crust to seal with the bottom crust.
- Brush the top crust with the egg wash and sprinkle with sugar.
- Bake in a preheated oven (400°F/200°C) for 20 minutes.
- Reduce oven temperature to 350°F/175°C and bake for an additional 30-40 minutes, or until the crust is golden brown and the filling is bubbling. Use a pie shield if the crust is browning too quickly.
- Let the pie cool completely on a wire rack before slicing and serving (at least 3 hours, preferably overnight for the filling to set). The best blueberry pie recipe is one that's cooled properly!
