This recipe comes directly from the book. It's a beauty. Loaded with inventive recipes and unique twists on the classes. Also, pie dough cookies!
1 recipe single crust pie dough (I'm partial to my latest recipe in Let's Stay In or you could use this one)
Buckwheat Pepita Streusel Topping
1⁄2 cup all-purpose flour
1⁄4 cup buckwheat flour
1⁄4 cup pepitas, toasted in a dry skillet
1 teaspoon ground cinnamon
1⁄4 cup packed light brown sugar
1⁄4 teaspoon kosher salt
1⁄2 cup (1 stick) unsalted butter, straight from the fridge
Pumpkin Pie Filling
1 (15-ounce) can pumpkin puree
3⁄4 cup buttermilk, at room temperature
3 large eggs, at room temperature
2 tablespoons Grade B maple syrup
2 tablespoons (1⁄4 stick) unsalted butter, melted and cooled
2 tablespoons fine yellow cornmeal
3⁄4 cup packed light brown sugar
1⁄2 teaspoon kosher salt
1⁄2 teaspoon ground cinnamon
1⁄2 teaspoon ground ginger
1 large egg, beaten
Roll out your chilled pie dough into a large rough circle. Roll the dough around your rolling pin, then lay over your pie dough. Cut any excess dough off then fold in the edges and crimp the dough between your fingers. Place in the freezer and chill for 15 minutes.
Preheat your oven to 450°F with the rack on the lowest level. Remove the pie crust from the freezer, tear off a square of parchment that is slightly larger than the pie shell, and gently fit it into the frozen crust. Fill the crust with sugar (yes, sugar, this is a genius tip I learned from Stella Parks from Bravetart. Read more about it here.) and place the pie pan on a baking sheet. Transfer the baking sheet to the oven and bake for 25 to 27 minutes. Check for doneness by peeling up a piece of parchment—the crimps should be light golden brown. Remove the baking sheet from the oven and transfer to a cooling rack. After 6 minutes, carefully remove the foil and beans. You did it! You are now ready to fill the pie.
Preheat your oven to 325°F. Line two baking sheets with parchment paper.
Make the streusel topping: In a mixing bowl, combine the all-purpose and buckwheat flours, pepitas, cinnamon, brown sugar, and salt. Place the butter in the bowl and coat on all sides with the flour mixture. Take a bench scraper and cut the butter into 1⁄2-inch cubes directly into the flour mixture in the bowl. Work to break up the cubes with your hands until they are lightly coated with the flour mixture. Continue to use the bench scraper to cut the cubes into smaller pieces—the idea is that you are cutting each cube in half.
Switch to a pastry blender and begin to cut in the butter with one hand while turning the bowl with the other. It’s important not to aim for the same spot at the bottom of the bowl with each movement, but to actually slice through butter every time. You’ll need to clean out the pastry blender every few turns of the bowl. Once most of the butter is incorporated, use your fingers to fully break down the butter until it is no longer visible. Be careful not to overwork the mixture at this point. Scatter the streusel over one of the parchment-lined baking sheets, distributing it evenly, and transfer the baking sheet to the oven. Bake for approximately 25 minutes, gently tossing the mixture with a spatula about halfway through. When the streusel is evenly browned and does not appear wet anymore, remove the baking sheet from the oven. Cool completely on a wire rack.
Make the filling: In a mixing bowl, combine the pumpkin, buttermilk, eggs, syrup, melted butter, cornmeal, brown sugar, salt, cinnamon, and ginger and whisk until well blended.
Place the blind-baked shell on the other parchment-lined baking sheet. Brush the crimped edge with the beaten egg. Pour the buttermilk-pumpkin filling into the pie shell until it reaches the bottom of the crimps. Transfer the baking sheet with the pie on it to the oven and bake for 50 to 60 minutes, until the edges are puffed and the center jiggles only slightly when shaken.
Remove the baking sheet from the oven and transfer the pie to a wire rack. Let cool for 15 minutes, then cover the pie with the streusel topping. Allow the pie to fully cool and set for another 4 to 6 hours. When the pie is at room temperature, slice it into 6 to 8 pieces and serve.
Store leftover pie, well wrapped in plastic wrap, in the refrigerator for up to 2 days.
