Prepare my sourdough pie crust recipe. After chilling, roll out the bottom crust and place it in a 9-inch deep pie dish and place it in the fridge to chill. Then, follow the instructions below. 1 Sourdough Pie Crust
To a large bowl, add the blueberries, sugar, flour, cornstarch, cinnamon, lemon juice, and lemon zest.
900 grams fresh blueberries, 150 grams sugar, 35 grams all-purpose flour, 6 grams cornstarch, 1 gram ground cinnamon, 30 grams lemon juice, zest of 1 lemon
Remove the second pie dough disc from the refrigerator and allow it to rest at room temperature for 10-15 minutes. This makes for easier rolling. Then roll it out as just before.
To create a lattice, take a pastry cutter, pizza cutter, or sharp knife to cut the pie dough into 1/2 – 1 inch pieces. Arrange the strips in vertical and horizontal rows, then lace them over and under each other. Or simply cover the sourdough blueberry pie with a dough circle and cut slits into the top crust. Pinch the edges with a fork or crimp with your fingers, if you desire.
In a small bowl, create an egg wash by mixing an egg with a splash of milk. Use a pastry brush to brush over the top of the dough. Sprinkle coarse sugar on top of the pie for an extra little touch of sweetness and crunch.

Preheat the oven to 375 degrees F. Place the pie pan on top of a rimmed baking sheet, just in case it bubbles over, and put it into the oven. Bake for 55-65 minutes, or until the pie is a deep golden brown and the juice from the blueberries are bubbling onto the pie crust. If the pie crust begins to brown to quickly, cover the top with a piece of aluminum foil. Remove from the oven and place it on a wire rack. Allow the pie to cool completely, about 3 hours, in order for it to set before slicing. Enjoy!
