Making this scrumptious Peach Mango Pie is straightforward if you follow these steps:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Prepare Filling: In a large bowl, combine sliced peaches and diced mangoes. Add sugar, lemon juice, cornstarch, vanilla extract, cinnamon, and salt. Toss gently to combine and set aside to let the flavors meld.
3. Prepare Crust: Roll out your pie crust and place one half in a 9-inch pie dish. Trim excess crust hanging over the edges.
4. Add Filling: Pour the fruit filling into the crust. Dot the top with small pieces of butter.
5. Cover Pie: Place the second pie crust over the filling. Seal the edges by crimping, and cut vents for steam to escape. Brush the top crust with the beaten egg for a golden finish.
6. Bake: Bake in the preheated oven for 45-50 minutes, or until the crust turns golden brown and the filling is bubbly. Check after 30 minutes and cover edges with foil if they get too dark.
7. Cool: Remove from the oven and allow to cool for 20-30 minutes before slicing.

These simple steps will guide you in creating an incredible Peach Mango Pie that delights taste buds and heart alike.
