To prepare the filling:
First, drain the can of peaches and pour juice into a medium-sized pot over medium heat. Sit the peaches aside.
Slightly heat the juice and then add the cornstarch.
Whisk until cornstarch lumps are almost gone.
Add the butter, sugar, vanilla, nutmeg, and cinnamon and whisk.
Let simmer for about 1 minute or until it slightly thickens.
Remove from the heat and return the peaches to the mixture.
To prepare crusts:
Preheat oven to 350 degrees.
Layer a medium-size baking dish with two buttered pie crusts.
Bake for 10 minutes or until slightly golden brown.
Remove the crust from the oven and pour the filling into pie crust.
Cover with the two remaining pie crusts.
Brush the crust with butter and sprinkle with nutmeg and sugar.
Bake for 30 minutes or until the top crust is golden brown.
Allow to rest for 10-15 minutes before serving.
