1 1/2 pounds nectarine , sliced 1/2 inch thick (4 3/4 cups)
1/3 cup granulated sugar
1 teaspoon fresh lemon juice
1/4 teaspoon coarse salt
1 tablespoon cornstarch
1 disk Pate Brisee
All-purpose flour, for surface
1 large egg, lightly beaten
Sanding sugar (optional), for sprinkling
Preheat oven to 375 degrees. Line a rimmed baking sheet with foil, then parchment. Stir together fruit, granulated sugar, lemon juice, salt, and cornstarch.
Roll out pate brisee into a 13-inch round,( or more small one ) about 1/8 inch thick, on a lightly floured surface. Transfer to baking sheet. Arrange fruit in center, leaving a 2-inch border. Fold over border to enclose fruit, leaving center open. Brush crust with egg, and sprinkle with sanding sugar.
Bake until golden brown and bubbling in center, about 35-40 minutes. Let it cool completely.
Ingredients for a Pate Brisee:
2 1/2 cups all-purpose flour
1 teaspoon coarse salt
1 teaspoon sugar
1 cup (2 sticks) chilled unsalted butter, cut in pieces
1/4 to 1/2 cup ice water
Place the flour, salt, and sugar in the bowl of a food processor, and process for a few seconds to combine. Add the butter, and process until the mixture resembles coarse meal, about 10 seconds. With the machine running, add the ice water in a slow, steady stream, through the feed tube, just until the dough holds together. Do not process for more than 30 seconds.
Turn the dough out onto a work surface. Divide in two. Place each half on a sheet of plastic wrap. Flatten, and form two discs. Wrap, and refrigerate at least 1 hour before using.
