Preheat oven to 425 degrees.
Brush 9 inch pie crust with egg wash. (Note: this keeps the filling from making your bottom soggy).
Place sliced peaches in a large mixing bowl. Add 1/8 cup of Bourbon (optional), then drizzle lemon juice. Toss gently.
Mix sugar, flour, nutmeg, cinnamon, and salt in a separate mixing bowl.
Next, pour flour mixture over peaches. Toss gently to get the peaches well coated.
Pour peaches mixture into pie crust.
Distribute cut pieces of butter evenly on top of pie filling.
Cover entire top with (other) pie dough.
Fold the crust edges under. Flute the edges to seal (you can watch a tutorial here). Use a fork to make imprints along the edge of the pie crust. It's also helpful to dip your fork in egg wash with each impression. Use can use water as well.
Cut about 5 slits on top of the crust for venting. Brush top of pie crust with remaining egg wash.
Bake on 425 for about 10 minutes then reduce to 350 degrees. Use the foil method to avoid burning your pie crust edges. See notes.
Bake for approximately 25 to 30 minutes or until you have a golden brown crust.
Allow the pie to cool 1 to 2 hours before serving.
Serve and enjoy with a scoop of vanilla ice cream!
