Maple Custard Pie

Ingredients

For the Pate Brisee Crust:

• All-purpose flour, for work surface
• 2 ½ cups all-purpose flour, plus more for dusting
• 1 teaspoon salt
• 1 cup (2 sticks) unsalted butter, cut into small pieces
• 1⁄4 to ½ cup ice water
• 1 large egg, lightly beaten

For the Filling:

• 1 cup pure maple syrup
• 2 cups heavy cream
• 1 large egg, plus 4 large egg yolks
• 1 teaspoon pure vanilla extract
• ½ teaspoon coarse salt
• Pinch freshly grated nutmeg

Instructions

1. 1
   Make the crust: Pulse flour and salt in a food processor to combine. Add butter; pulse until mixture resembles coarse crumbs with some larger pieces remaining. Evenly drizzle 1/4 cup ice water over mixture. Pulse until dough is crumbly but holds together when squeezed. If dough is too dry, add up to 1/4 cup more ice water, 1 tablespoon at a time, and pulse to combine.
2. 2
   Turn out dough onto a floured surface and divide dough in half, then shape each half into a disk. Wrap each half in plastic and refrigerate until firm, about 1 hour or up to 1 day. (Dough can be frozen up to 1 month; thaw overnight in refrigerator before using.)
3. 3
   Prepare the crust: Roll out 1 disk of dough to just under 1/4 inch thick on a lightly floured surface and fit into a 9-inch glass pie plate. Trim excess, leaving a 1-inch overhang; fold edges under and set aside. Roll out half of remaining disk of dough (reserve remaining dough for another use) to just under 1/4 inch thick, cut out small leaf shapes, and mark veins with the back of a knife, if desired. Brush edges of the pie crust with egg wash and apply leaves. Freeze for at least 1 hour.
4. 4
   Preheat oven to 375 degrees. Brush pastry leaves with more egg wash. Line crust with parchment and fill with pie weights or dried beans. Bake until crust is set, 25 to 30 minutes. Remove pie weights and parchment, and continue to bake until bottom of crust is lightly browned, about 10 minutes more. Let cool completely on a wire rack, about 1 hour.
5. 5
   Make the filling: Reduce oven temperature to 300 degrees. Place syrup in a large saucepan over medium-high and cook until reduced by a quarter, 5 to 7 minutes. Stir in cream and bring to a simmer; remove from heat.
6. 6
   In a medium bowl, whisk together egg, yolks, vanilla, salt, and nutmeg. Whisking constantly, slowly add cream mixture to egg mixture, and strain custard mixture through a fine-mesh sieve into a large glass measuring cup.
7. 7
   Pour custard into crust and place on a rimmed baking sheet. Bake until filling is just set but still slightly wobbly, 45 to 60 minutes. Let cool to room temperature before serving.
