Ingredients:
- 2.5 cups (315g) all-purpose flour
- 1 cup (225g) unsalted butter, chilled and cubed
- 1 tsp (6g) salt
- 1 tbsp (12g) granulated sugar
- 6-8 tbsp (90-120ml) ice water
- 5 cups (850g) fresh peaches, peeled and sliced
- 0.75 cup (150g) granulated sugar
- 0.25 cup (30g) cornstarch
- 1 tbsp (6g) ground cinnamon
- 1 tbsp (15ml) lemon juice
- 1 tbsp (14g) unsalted butter, diced
- 1 large egg
- 1 tbsp (12g) coarse sugar
Instructions:
- Whisk flour, salt, and sugar in a large bowl.
- Work the chilled butter into the flour using a pastry cutter until the mixture resembles coarse crumbs with some pea-sized lumps.
- Add ice water one tablespoon at a time, stirring until the dough just holds together.
- Divide dough into two discs, wrap in plastic, and chill for 30 minutes.
- Toss sliced peaches with lemon juice, sugar, cornstarch, and cinnamon in a large bowl and let sit for 10 minutes.
- On a floured surface, roll the first dough disc to a 12-inch circle and fit it into a 9-inch deep-dish pie plate.
- Pour the peach mixture into the crust, dotting the top with the diced butter pieces.
- Roll the second disc, cut into strips, and weave them across the top to create a lattice.
- Trim and crimp the edges, brush with beaten egg, and sprinkle with coarse sugar.
- Place on a baking sheet and bake at 400°F (200°C) for 20 minutes, then reduce heat to 375°F (190°C) and bake for another 40–45 minutes until the crust is mahogany-colored and filling is bubbling.
