Instructions
Make the Crust: In a large bowl, whisk flour, sugar, and salt. Cut in cold butter until mixture resembles coarse crumbs with pea-sized pieces. Mix vinegar with 3 tbsp ice water; drizzle over flour and stir until dough just holds together. If too dry, add ½–1 tbsp more water. Shape into a disk.
Prepare the Filling: Gently toss strawberries, blueberries, raspberries, and blackberries with sugar, cornstarch, lemon zest, lemon juice, and vanilla (if using). Let sit 5 minutes.
Preheat Oven: Preheat to 400°F (200°C). Line a baking sheet with parchment paper.
Roll Out Dough: On a lightly floured surface or pastry mat, roll dough into a 12-inch circle, about ⅛-inch thick. Transfer to baking sheet.
Assemble Galette: Spoon berries into center, leaving a 1½ – 2-inch border. Dot with butter cubes if using. Fold dough edges over filling, pleating as needed.
Apply Egg Wash: Whisk egg and milk; brush over crust edges. Sprinkle with coarse sugar.
Bake: Bake 30–40 minutes, until crust is golden and filling bubbles. Check at 30 minutes. Cool 10–15 minutes.
Serve: Slice and serve warm or at room temperature with ice cream, whipped cream, or mint.
Notes
No-Chill Dough: Skipping chilling works but may make dough slightly sticky. Use 3 tbsp water initially to avoid wetness. Chill for 30 minutes if time allows for easier rolling.Frozen Berries: Thaw and drain well, patting dry to prevent soggy crust.Blackberries: If tart, increase sugar to ⅓ cup. Halve large berries.Cornstarch: Use 2 ½ tsp for juicy berries to thicken filling.Storage: Refrigerate leftovers for up to 3 days. Reheat at 350°F for 5–10 minutes.
