Instructions
In a large bowl, combine flour, sugar, and salt. Cut in cold butter and shortening using a pastry blender until mixture resembles coarse crumbs with some pea-sized pieces.
Drizzle ice water 1 tablespoon at a time, stirring gently until dough holds together when pressed. Divide into two disks, wrap in plastic, and refrigerate for at least 1 hour.
In a large bowl, combine blueberries with sugar, cornstarch, flour, lemon zest, lemon juice, cinnamon, allspice, and salt. Toss until berries are evenly coated.
Preheat oven to 425°F with a foil-lined baking sheet on the lower rack. Roll out one dough disk into a 12-inch circle and transfer to a 9-inch deep-dish pie plate.
Roll out the second dough disk into an 11-inch circle on parchment paper. Cut into 1-inch wide strips using a knife or pastry wheel.
Pour the blueberry filling into the bottom crust and dot with butter pieces. Weave the dough strips into a lattice top, trimming and crimping the edges.
Brush the lattice with egg wash and sprinkle with coarse sugar. Bake on the preheated sheet at 425°F for 15 minutes, then reduce to 375°F and bake 40-50 minutes until bubbling in the center.
Cool the pie on a wire rack for at least 3 hours before slicing to allow the filling to set completely.
Notes
Use cold fat and ice water for a flaky crust. Warm ingredients will make the dough tough.
Do not overwork the pie dough. Mix just until it comes together to avoid a dense crust.
Dry blueberries thoroughly before using. Excess moisture leads to a runny filling.
Bake until the filling bubbles actively in the center. This ensures the thickener has cooked properly.
Let the pie cool completely for at least 3 hours before slicing. The filling sets as it cools.
If the crust edges brown too quickly, cover them with foil or a pie shield halfway through baking.
To use frozen blueberries, add them straight from the freezer and increase cornstarch by 1 tablespoon.
Store at room temperature for up to 2 days or in the refrigerator for up to 5-7 days.
Make ahead: freeze unbaked assembled pie for up to 3 months. Bake from frozen at 425°F for 20 minutes, then 375°F for 60-70 minutes.
Serve with vanilla ice cream or whipped cream for the classic pairing.
