Instructions:
- Whisk flour, salt, and sugar in a bowl.

- Add ice water one tablespoon at a time, stirring until the dough just holds together. Do not over-mix.
- Form the dough into a disk, wrap in plastic, and refrigerate for at least 1 hour.
- Roll the dough on a floured surface and press it firmly into the bottom and up the sides of a 9-inch deep-dish pie plate.
- In a large bowl, combine sliced peaches, lemon juice, and melted butter.
- Stir in brown sugar, granulated sugar, cinnamon, and nutmeg.
- Sprinkle the cornstarch over the filling and toss to coat evenly.
