Ingredients:
- 2 ½ cups all-purpose flour (315g)
- 1 cup unsalted butter, chilled and cubed (225g)
- 1 tbsp granulated sugar (12g)
- 1 tsp fine sea salt (6g)
- 6 tbsp ice water (90ml)
- 1 tsp apple cider vinegar (5ml)
- 1 large egg yolk
- 1 tbsp heavy cream (15ml)
- 1 tbsp coarse sanding sugar (12g)
Instructions:
- Whisk together the all-purpose flour, granulated sugar, and fine sea salt in a chilled mixing bowl until the seasoning is evenly distributed.
- Add the cubed, ice-cold butter to the flour mixture. Use a pastry cutter to work the butter into the flour until the mixture resembles coarse crumbs with some pea-sized chunks of butter still visible.
- Mix the apple cider vinegar into the ice water. Drizzle the water into the dough in 1-tablespoon increments, tossing with a fork after each addition, until the dough just begins to clump together.
- Gently press the dough into a disk shape, wrap tightly in plastic wrap, and refrigerate for at least 1 hour.
- On a floured surface, roll the chilled dough from the center outward into a 12-inch circle. Carefully drape the dough over the peach filling, trim the edges, and crimp.
- Brush the top of the crust with a mixture of egg yolk and heavy cream, then sprinkle with coarse sanding sugar.
- Bake until the crust is a deep mahogany gold.
