1 1/4 cup all-purpose flour, plus more for rolling (see Cook's Note)
1 tablespoon granulated sugar
1/4 teaspoon kosher salt
1 stick (8 tablespoons) cold unsalted butter, diced
1 large egg beaten with 1 tablespoon cold water
8 ounces cream cheese, at room temperature
2 tablespoons plus 1/3 cup granulated sugar
1/2 teaspoon vanilla extract
1 large egg, separated
Pinch of kosher salt
2 cups strawberries, hulled, then halved or quartered depending on the size (about 1-inch pieces)
1 tablespoon cornstarch
Coarse sugar, for sprinkling
When measuring flour, we spoon it into a dry measuring cup and level off the excess. (Scooping directly from the bag compacts the flour, resulting in dry baked goods.)
