INGREDIENTS
8 ounces all-purpose flour (1 2/3 cups; 225g), plus more for dusting
1/2 ounce sugar (1 tablespoon; 15g)
1 teaspoon (4g) Diamond Crystal kosher salt; for table salt, use half as much by volume or use the same weight
8 ounces unsalted butter (2 sticks; 225g), cold
4 ounces cold water (1/2 cup; 115g)
DIRECTIONS
For the Dough: Whisk flour, sugar, and salt together in a medium bowl. Cut butter into 1/2-inch cubes (this size is important, as smaller pieces will melt too fast) and toss with flour mixture to break up the pieces. With your fingertips, smash each cube flat—that's it! No rubbing or cutting. Stir in water, then knead dough against the sides of the bowl until it comes together in a shaggy ball. Dough temperature should register between 65 and 70°F (18 and 21°C); if not, refrigerate briefly before rolling and folding (see note above).
Make the Layers: On a generously floured work surface, roll dough into a roughly 10- by 15-inch rectangle. Fold the 10-inch sides to the center, then close the newly formed packet like a book. Fold in half once more, bringing the short sides together to create a thick block. Divide in half with a sharp knife or bench scraper. Dough temperature should still be somewhere between 65 and 70°F (18 and 21°C); if not, refrigerate briefly before proceeding (see note above).
For Single-Crusted Pies: Using as much flour as needed, roll one piece into a 14-inch circle and drape across a 9-inch pie plate; it will be super easy to lift by hand. Dust off excess flour with a pastry brush, using it to nestle dough into the very corners of the pan. With scissors or kitchen shears, trim the edge so that it overhangs by 1 1/4 inches all around. Fold overhang over itself to create a thick border that sits atop the rim of the pan. Crimp or shape crust as desired. Repeat with remaining dough. Wrap with plastic and refrigerate at least 2 hours and up to overnight. Use as directed in your favorite recipe.
For a Double-Crusted Pie: Using as much flour as needed, roll one piece into a 14-inch circle and drape across a 9-inch pie plate; it will be super easy to lift by hand. Dust off excess flour with a pastry brush, using it to nestle dough into the very corners of the pan. With scissors or kitchen shears, trim the edge so that it overhangs by 1 inch all around. For a solid top crust, roll remaining dough as before, or roll into a 9- by 15-inch rectangle for a lattice-top pie. Transfer the entire sheet, uncut, to a baking sheet or parchment-lined cutting board. (The parchment will prevent dough from absorbing any savory odors from the board.) Wrap both portions in plastic and refrigerate at least 2 hours and up to overnight. Use as directed in your favorite recipe.
For a Blind-Baked Pie: Adjust oven rack to lower-middle position and preheat to 350°F (177°C). Line chilled pie shell with a large sheet of aluminum foil, pressing so it conforms to the curves of the plate (a second sheet of aluminum may be needed for full coverage). Fill to the brim with sugar, transfer to a half sheet pan, and bake until fully set and golden around the edges, 60 to 75 minutes. Fold long sides of foil toward the middle, gather short sides, and use both hands to carefully transfer sugar to a heat-safe bowl. Let sugar cool to room temperature. If needed, continue baking crust a few minutes more to brown along the bottom. A full explanation of this process can be found here.
For the Filling:
28 ounces pitted cherries (5 heaping cups; 790g), from about 2 pounds whole fruit (6 heaping cups; 910g) (see note above)
1 ounce fresh lemon juice (2 tablespoons; 30g) from 1 small lemon
7 ounces sugar (1 cup; 195g)
3/4 teaspoon (3g) Diamond Crystal kosher salt; for table salt, use half as much by volume or use the same weight
1 1/2 ounces tapioca starch, such as Bob's Red Mill (1/3 cup plus 1 teaspoon; 40g)
Old-Fashioned Flaky Pie Dough, rolled and chilled as per the directions for a double crust
DIRECTIONS
For the Filling: Combine pitted cherries, lemon juice, sugar, salt, and tapioca starch in a large bowl, folding with a flexible spatula until well combined. Scrape into prepared pie shell and top with remaining dough, using a solid sheet, cutouts, or a lattice-top design. (Check out my tutorials here.) Trim away excess dough and refrigerate pie to ensure top crust is completely chilled, about 30 minutes. Meanwhile, adjust oven rack to lower-middle position and preheat to 400°F.
Place chilled pie on a parchment-lined rimmed baking sheet. Bake until crust is golden, about 1 hour, then loosely cover with tented foil. (Alternatively, an empty baking sheet can be placed on the topmost rack of the oven to serve as a shield.) Continue baking until filling is bubbling even in the very center of the pie, about 15 minutes more. If crust completely covers filling, bake until pie reaches an internal temperature of 213°F on a digital thermometer. The time can vary considerably depending on the thickness and type of pie plate, the amount of top crust, how long the pie was refrigerated, et cetera.
To Serve: Cool pie until no warmer than 85°F on a digital thermometer, about 3 hours depending on the type of pie plate (at higher temperatures, filling will be runny and thin). Slice into wedges with a sharp knife, pressing firmly against bottom and sides of pie plate to ensure the under-crust is completely cut. If you like, serve with Cherry Pit Whipped Cream. Wrapped in foil, leftovers will keep up to 3 days at room temperature; warm 10 minutes in a 350°F oven to revive crust before serving.
