Sour Cherry Pie

Preparation

1. Crust:

   Step 1

   Pulse almond flour, granulated sugar, salt, and 2 1/2 cups all-purpose flour in a food processor. Add butter and pulse until mixture resembles coarse cornmeal.

   Step 2

   Whisk egg yolks and 1/4 cup ice water in a small bowl and drizzle over flour mixture. Pulse, drizzling in more ice water as needed, until dough just comes together (a few dry spots are okay).

   Step 3

   Gently knead dough on a lightly floured surface until no dry spots remain, about 1 minute. Divide dough in half and pat each piece into a disk; wrap in plastic. Chill at least 2 hours.

   Step 4

   Do ahead: Dough can be made 3 days ahead. Keep chilled.

2. Filling and assembly:

   Step 5

   Preheat oven to 425°F. Let dough sit at room temperature to soften slightly, about 5 minutes. Roll out 1 disk of dough on a lightly floured surface to a 12" round.

   Step 6

   Transfer to a parchment-lined baking sheet and chill. Repeat with remaining disk of dough.

   Step 7

   Combine granulated sugar and lime zest in a large bowl, rubbing together with your fingertips to release oils in zest. Whisk in cornstarch and salt until there are no lumps in cornstarch. Add cherries and toss to coat.

   Step 8

   Carefully transfer 1 crust to a 9" pie dish. Lift up edges and allow dough to slump down into dish. Trim edges to even out crust if needed. Scrape in cherry filling.

   Step 9

   Using a 3/4"-diameter pastry tip or cookie cutter, punch out holes in remaining crust, covering an area just smaller than the diameter of pie dish. Place over filling. Fold edge of top crust underneath edge of bottom crust and press together to seal. Crimp as desired. (Alternatively, assemble pie, then cut X's or slits into crust.)

   Step 10

   Brush crust with egg and sprinkle with demerara sugar. Chill pie until crust is firm, 20-30 minutes.

   Step 11

   Place pie on a parchment-or foil-lined baking sheet. Bake until crust is golden, about 30 minutes. Reduce oven temperature to 350°F and bake, tenting with foil if crust is browning too quickly, until juices are bubbling and crust is deep golden brown, 50-60 minutes longer. Transfer to a wire rack and let cool at least 4 hours before slicing.

   Step 12

   Do ahead: Pie can be baked 1 day ahead. Store tightly wrapped at room temperature.
