- Wash the blackberries thoroughly to remove any dirt or stems.
- Peel and slice the peaches, then gently toss them with lemon juice to prevent browning.
2. **Combine Fruits:**
- In a large mixing bowl, combine the sliced peaches and blackberries.
- Add sugar, cinnamon, nutmeg, salt, and cornstarch (if using) to the fruit mixture. Stir well until evenly coated.
- Allow this mixture to sit for 10-15 minutes so that the fruits can release some of their juices.
3. **Prepare Pie Crust:**
- Preheat your oven to 425°F (220°C).
- Roll out the pie crust on a lightly floured surface until it is about 12 inches in diameter.
- Carefully transfer the rolled-out dough into a 9-inch pie dish, trimming any excess edges.
4. **Fill Pie Crust:**
- Pour the fruit mixture evenly into the prepared pie shell.
- Smooth out the filling and make sure there are no lumps or gaps.
5. **Top with Crust:**
- Roll out an additional piece of dough to cover the top of your pie, trimming it to fit snugly over the filling.
- Use a fork to crimp the edges of the dough to seal them together. Trim off any excess dough and cut several small vents into the top crust to allow steam to escape during baking.
6. **Egg Wash:**
- Lightly brush the top crust with the egg wash mixture using a pastry brush.
- Sprinkle some coarse sugar over the top if desired for added texture.
7. **Bake:**
- Place the pie on a baking sheet and bake in the preheated oven for 45-50 minutes, or until the edges are golden brown and the filling is bubbly.
- If the crust begins to brown too quickly, cover it loosely with aluminum foil.
8. **Cool and Serve:**
- Remove from the oven and let the pie cool on a wire rack for at least 1 hour before serving.
- Enjoy your delicious Blackberry Peach Pie while it’s still warm!
