Directions

Preheat the oven to 425°F. Line a baking sheet with parchment paper.

Lightly flour your work surface then unfold the puff pastry. Using a rolling pin, roll it until it’s a 10-inch square. Round off the corners (if desired) then transfer the pastry onto the prepared baking sheet.

In a medium bowl, stir together the strawberries, peaches, sugar, lemon zest, lemon juice and cornstarch. Transfer the fruit mixture into the center of the pastry, leaving a 2-inch border around the edges. Fold the pastry edges up and over so that they are overlapping each other and press them lightly together. Brush the top of the galette with the egg wash then sprinkle it with sanding sugar (optional). Bake the galette until the pastry is golden brown and the filling is bubbling, 25 to 30 minutes.

Remove the galette from the oven and let it cool completely before slicing and serving. Original recipe from @justataste
