Ingredients:
- 315g all-purpose flour
- 225g unsalted butter, frozen and grated
- 90ml ice water
- 800g fresh blueberries
- 150g granulated sugar
- 35g cornstarch
- 1 medium lemon, zested and juiced
- 3g salt
- 1g ground cinnamon
Instructions:
- Prep the butter. Grate 225g frozen unsalted butter using the large holes of a box grater.
- Mix the dry base. Combine 315g all purpose flour, 3g salt, and the grated butter in a large bowl.
- Hydrate the dough. Add 90ml ice water one tablespoon at a time, tossing with a fork until the dough just holds together when squeezed.
- Chill the pastry. Divide the dough into two disks, wrap tightly, and refrigerate for at least 30 minutes.
- Prepare the berries. Toss 800g fresh blueberries with 150g granulated sugar, 35g cornstarch, 1g cinnamon, and the zest/juice of 1 lemon.
- Roll the base. Roll out one disk on a floured surface to 12 inches and fit into your pie plate.
- Fill the pie. Pour the blueberry mixture into the crust, ensuring it is even.
- Top and seal. Roll the second disk, place over the berries, and crimp the edges tightly until the seal is completely airtight.
- Vents and wash. Cut 4-5 slits in the top crust and brush with a little water or milk for color.
- Bake high then low. Start at 425°F for 20 minutes, then drop to 375°F for 35 minutes until the juices are bubbling thick and slow.
