Peach and Blueberry Galette

Susan from Food Blogga

Serves 8
Dough:
1 3/4 cups all-purpose flour
1/3 cup granulated sugar
1/4 cup coarse cornmeal
1/4 teaspoon salt
1/2 cup cold butter, cut into small pieces
1/3 cup fat-free buttermilk

Fruit Filling:
2 1/2 cups fresh blueberries
3 cups thinly sliced peaches (about 3 large)
1/2 cup granulated sugar
1/4 cup light brown sugar
1 teaspoon ground cinnamon
1 teaspoon pure vanilla extract
1 teaspoon fresh minced ginger
3 tablespoons cornstarch

1 egg white
2 tablespoons fat-free milk
1 tablespoon turbinado sugar

To make the dough, combine flour, sugar, cornmeal, and salt in a processor; pulse 2-3 times. Add butter and pulse 4-5 times, or until mixture resembles coarse meal. With the processor running, slowing pour the buttermilk through the chute, processing until the dough forms a ball. Remove the dough ball and adhere any remaining pieces of dough to it, then wrap in plastic wrap or parchment paper. Refrigerate for 30-35 minutes.

Center a rack in the oven and preheat to 350 degrees F.

To make the fruit filling, combine all ingredients in a large bowl, and toss gently, making sure that the cornstarch is coating the fruit. (This will prevent too much juice from leaking out while the galette bakes.)

Remove the dough from the refrigerator and place on a sheet of parchment paper. Starting at the center of the dough, roll out, forming a 14-15-inch wide circle. Place the dough with parchment paper on a baking sheet. Add the fruit mixture to the center of the dough, leaving a 2-inch border. Fold the border over the filling, overlapping where necessary and pressing gently to adhere the folds.

Lightly whisk the egg white and milk in a small bowl. Brush dough with egg wash, and sprinkle with turbinado sugar. Bake for 1 hour, or until crust is golden brown and the filling is bubbly. Transfer the baking sheet to a wire rack to cool for at least 20 minutes. (Cutting it too quickly will cause the dough to crack). It's best served at room temperature or slightly warm. Optional garnishes include vanilla ice cream, a dollop of creme fraiche, or freshly whipped cream.
