Creating a Blueberry Pie can be fun and rewarding. Here’s how to do it:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Prepare Pie Crust: Roll out one pie crust and fit it into a 9-inch pie pan. Press it down gently to fit the bottom and sides.
3. Mix Filling: In a large bowl, combine the blueberries, granulated sugar, cornstarch, lemon juice, lemon zest, and ground cinnamon. Gently toss until the blueberries are well-coated.
4. Fill Pie Crust: Pour the blueberry filling into the prepared pie crust, spreading it evenly.
5. Add Butter: Dot the filling with small pieces of butter to enhance flavor.
6. Top Crust: Roll out the second pie crust and place it over the blueberry mixture. Seal the edges by crimping or pressing with a fork to ensure no filling escapes.
7. Cut Vents: Make several small slits in the top crust to allow steam to escape.
8. Apply Egg Wash: Brush the top crust with the beaten egg for a golden finish.
9. Bake: Place the pie in the oven and bake for 45-50 minutes, or until the crust is golden and the filling is bubbly.
10. Cool: Remove from the oven and let it cool on a wire rack for at least 1 hour before slicing.

Following these steps will guide you to create a stunning Blueberry Pie that everyone will love!
