Instructions
In a large bowl, whisk together flour and salt for the crust. Cut in very cold butter with a pastry cutter until mixture resembles coarse crumbs with pea-sized bits.
Drizzle in ice water, 1 tablespoon at a time, tossing with a fork until dough just begins to clump. Divide dough in half, form into disks, wrap in plastic, and refrigerate for at least 1 hour.
Preheat oven to 400°F. Gently combine olallieberries, sugar, cornstarch, lemon juice, lemon zest, and salt in a large bowl. Let sit for 15 minutes to draw out juices.
Roll one dough disk into a 12-inch circle and transfer to a 9-inch pie pan. Trim overhang to 1 inch and refrigerate while rolling top crust.
Pour filling into chilled crust and dot with 2 tablespoons of butter pieces. Roll second dough disk and place over filling, crimp edges, and cut slits in top.
Brush with egg wash and sprinkle with sugar. Place on baking sheet and bake at 400°F for 15 minutes, then reduce to 375°F for 35-40 minutes until golden and bubbly.
Allow pie to cool on a wire rack for at least 3 hours before slicing to let the filling set properly. Serve at room temperature or slightly warm.
Notes
Keep all crust ingredients as cold as possible for the flakiest results; chill the flour and bowl if needed.
If using frozen olallieberries, do not thaw and add an extra tablespoon of cornstarch to compensate for extra moisture.
Let the pie cool completely for at least 3 hours — cutting it warm will cause the filling to run.
Bake on a rimmed baking sheet to catch any drips and avoid oven messes.
Use a glass pie pan to easily check that the bottom crust is fully browned and crisp.
If the crust edges brown too quickly, cover them with a pie crust shield or foil during baking.
You can substitute a mix of blackberries and raspberries if olallieberries are unavailable.
This pie freezes beautifully: wrap it tightly and freeze for up to 3 months.
For a twist, add a half teaspoon of cinnamon to the filling or top with a crumb topping.
Store covered at room temperature for up to 2 days or refrigerate for up to 5 days.
