Creating a Strawberry Peach Galette is an enjoyable process with these straightforward steps:

1. Make the Crust:
– In a mixing bowl, combine the flour, sugar, and salt.
– Add the chilled butter cubes. Using a pastry cutter or your fingers, mix until the mixture resembles coarse crumbs.
– Gradually add the ice water, one tablespoon at a time, mixing just until the dough comes together. Form into a disk, wrap in plastic, and refrigerate for at least 30 minutes.

2. Prepare the Filling:
– In another bowl, combine the sliced strawberries, sliced peaches, lemon juice, vanilla extract, cornstarch, and a sprinkle of sugar. Toss gently to combine, and let it sit for about 10-15 minutes.

3. Preheat the Oven:
– Preheat your oven to 375°F (190°C).

4. Roll Out the Dough:
– On a lightly floured surface, roll out the chilled dough into a rough 12-inch circle. Transfer to a parchment-lined baking sheet.

5. Add the Filling:
– Spoon the fruit mixture into the center of the dough, leaving about a 2-inch border around the edges.

6. Fold the Edges:
– Gently fold the edges of the dough over the filling, pleating as you go. The center will remain open, showcasing the delicious fruit.

7. Apply Egg Wash:
– Beat an egg and brush it over the exposed crust. Sprinkle a bit of sugar on top for extra sweetness and crunch.

8. Bake:
– Place the galette in the oven and bake for 40-50 minutes, or until the crust is golden brown and the fruit is bubbling.

9. Cool:
– After baking, remove the galette from the oven and let it cool on the baking sheet for 10-15 minutes before slicing.
