Start by rolling out your bottom crust and fitting it snugly into your pie dish, then pop it in the refrigerator to chill while you work on the filling.

In a large bowl, gently combine the wild blueberries (6 cups) with granulated sugar (3/4 cup), brown sugar (2 tablespoons) if using, lemon zest (1 tablespoon), lemon juice (2 tablespoons), and salt (1/4 teaspoon). In a separate small bowl, whisk together the cornstarch (3 tablespoons) and flour (2 tablespoons) until completely smooth, then gently fold this mixture into the berries to avoid bursting too many of those precious little gems. Suppose you want extra insurance against a runny pie.

In that case, you can warm about half of this berry mixture in a saucepan over medium heat, stirring carefully until it just starts to thicken and bubble, then combine it back with the remaining raw berries for the perfect balance of set filling and fresh fruit texture.

Preheat your oven to 425°F and retrieve your chilled bottom crust from the fridge. Pour the berry filling into the prepared crust, making sure to scrape every last bit from the bowl, then dot the surface evenly with small pieces of butter (3 tablespoons).

Cover with your top crust or create a lattice pattern if you’re feeling fancy, then seal and crimp the edges firmly to prevent any delicious filling from escaping during baking.

Brush the entire top surface with beaten egg (1 egg) and sprinkle with coarse sugar (1 tablespoon) if you want that bakery-perfect sparkle. Slide the pie into your preheated oven and bake for 20 to 25 minutes until the top crust begins to set and take on some color.

Reduce the temperature to 375°F to 400°F and continue baking for another 40 to 50 minutes, watching for the filling to bubble enthusiastically in the center and the crust to turn a deep, gorgeous golden brown. If the edges start browning too quickly, tent them with strips of aluminum foil to prevent burning.

Once done, remove the pie and let it cool completely at room temperature for at least 4 hours before even thinking about slicing into it.
