Ingredients
10 ounces Bing cherries, pitted and halved
10 ounces golden cherries, pitted and halved
12 ounces sour cherries, pitted
1/2 cup granulated sugar
1 1/2 tablespoons cornstarch
Pinch of salt
1 large egg
1 tablespoon heavy cream
All-purpose flour, for work surface
Pate Brisee for Three-Cherry Tart
Fine sanding sugar, for sprinkling
Preparation
Preheat oven to 400 degrees. Toss cherries, granulated sugar, cornstarch, and salt in a bowl; set aside. Whisk egg and cream in a small bowl; set egg wash aside.
Turn out dough onto a lightly floured work surface. Roll into a 16-inch round, about 1/8 inch thick. Transfer to a large baking sheet lined with parchment paper. Spread cherry mixture over dough, leaving a 2-inch border around edge. Fold dough over edges of filling. Brush dough with egg wash; sprinkle with sanding sugar. Refrigerate 15 minutes.
Bake tart until edges are dark golden brown and cherries are bubbling and cooked through, about 1 hour. Let cool on sheet on a wire rack 15 minutes. Transfer tart to rack to cool completely.
