Peach & Blackberry Sourdough Galette

Made with backyard peaches (or market finds!), this freeform galette is one of our family’s favorite ways to use up extra dough and sweet fruit.
What you need:
175g All Purpose Flour
7g Granulated Sugar
3g Fine Sea Salt
113g Unsalted Butter, Cold
115g Sourdough Starter
37g Cold Water
For the filling:
450g Sliced Peaches
150g Blackberries
14g Fresh Lemon Juice
50g Granulated Sugar
5g Cornstarch
3g Fine Sea Salt
Make The Crust: In a large bowl, whisk together the flour, sugar and salt. Cut the butter into small cubes. Add the butter and lightly toss to coat with flour. Using your hands, cut the butter into the flour until the butter is the size of small peas. Add the sourdough starter and water. Stir with a spatula until well combined. The dough should just come together, but if its still very dry, add more water.
Scrape the dough onto a clean work surface and gather and gently knead it into a disc shape. Tightly wrap the disc in plastic wrap and refrigerate for 2 hours or overnight before rolling out.
Make The Filling: In a large bowl, combine the peaches, blackberries, lemon juice, sugar, cornstarch and salt.
Preheat the over to 400F. Line a 13 x 18 inch half-sheet pan with parchment.
Unwrap the dough and place it on a lightly floured work surface. Using a rolling pin, roll the dough out into a round about 12 inches in diameter. Transfer to the lined sheet pan. Scoop the filling into the centre of the crust, leaving 2-inch border all around. Then fold the border of the crust up over the filling in a series of pleats as you make your way around. Refrigerate for 30 minutes.
To Finish: Bake for 40 minutes or until the juices are bubbling and the crust is golden brown. Let cool for 25-35 minutes and serve warm.
