  • 4 tbsp (60ml) ice water
  • 6 cups (900g) fresh peaches, peeled and sliced

  • ½ cup (113g) unsalted butter, softened to room temperature

Instructions:

  1. Whisk flour, salt, and sugar in a bowl.
  2. Use a pastry cutter or fork to work the chilled butter into the flour until it looks like coarse crumbs with pea-sized lumps.
  3. Add ice water one tablespoon at a time, stirring until the dough just holds together. Do not over-mix.
  4. Form the dough into a disk, wrap in plastic, and refrigerate for at least 1 hour.
  5. 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.
  6. In a large bowl, combine sliced peaches, lemon juice, and melted butter.
  7. Stir in brown sugar, granulated sugar, cinnamon, and nutmeg.
  8. Sprinkle the cornstarch over the filling and toss to coat evenly.
