Ingredients
Method
- Make the dough: Whisk the flour, sugar and salt together. Cut in the cold butter until pea sized pieces remain, then add ice water one tablespoon at a time until a shaggy dough just holds together.
- Chill: Press the dough into a disc, wrap it, and chill for 30 minutes.
- Make the filling: Toss the sliced peaches and strawberries with the sugar, cornstarch and lemon juice. Let the bowl sit and get glossy while the dough chills.

- Roll: Roll the dough out on parchment into a rough 12 inch circle. If it cracks at the edges, let it warm for five minutes first. Rough is correct.
- Fill and fold: Pile the fruit in the middle, leaving a 2 inch border. Fold the edges over wherever they want to go.

- Finish: Brush the crust with the beaten egg and scatter coarse sugar over the folds.
- Bake: Bake at 375F (190C) for 35 to 40 minutes, until the crust is deeply golden and the fruit bubbles at the center.

- Rest and serve: Cool for 20 minutes on the pan. Serve warm, with something cold melting on top.
Notes
Fruit: Any mostly ripe stone fruit works here. Swap the strawberries for more peaches, or the other way around. About 3 cups of fruit total is the sweet spot.
Hot day tip: If the butter starts glistening while you roll, slide the parchment onto a tray and give it 10 minutes in the fridge before folding.
Make ahead: The dough disc keeps in the fridge for 2 days or the freezer for a month. Thaw overnight in the fridge before rolling.
Storage: Covered at room temperature the day it is baked, then in the fridge for up to 3 days. Rewarm slices in a low oven so the crust stays crisp.
