Instructions

PIE DOUGH

1. In a food processor, process ¾ cup flour, sugar and salt until combined, about 5 seconds. Add the butter and shortening on top and continue to process until combined and mixture starts to clump, with no bits of flour remaining, about 10 seconds.
2. Scrape down the bowl to evenly distribute the dough. Add remaining ½ cup flour to the dough and pulse until the dough had broken up and is evenly distributed around the bowl, about 4 to 6 pulses.
3. Transfer dough to a large bowl and sprinkle vodka and ice water on top. Stir with a rubber spatula, pressing the dough together until it comes together.
4. Invert the dough onto a piece of plastic wrap and flatten and tightly wrap into a 4-inch disk. Refrigerate for 1 hour. Let dough sit on counter for 10 minutes before rolling out. The dough can be refrigerated for up to 2 days, and stored in the freezer for up to 1 month. If frozen, let thaw completely on the counter before rolling out.
5. Adjust your oven rack to the middle position and preheat your oven to 425 degrees. Roll the dough into a 12-inch circle on a floured counter. After rolling the dough out, loosely roll it around your rolling pin and gently unroll it onto your 9 inch pie plate. Gently ease the dough into the lower creases of the pan and press lightly to adhere it to the sides and bottom of the pan. Leave the excess dough hanging over the sides of the pan in place. Wrap the dough-lined pie plate loosely in plastic wrap and refrigerate until the dough it firm, about 30 minutes.
6. Trim the dough edges leaving a ½-inch overhang and tuck overhang underneath itself. Crimp the dough around the edge in a decorative fashion. Wrap dough lined pie plate loosely with plastic wrap and refrigerate for 15 minutes before using.
7. Line the chilled pie shell with a double layer of aluminum foil, covering the edges to prevent burning and fill with pie weights or dry beans.
8. Bake your pie shell until the pie dough looks dry and is pale in color about 15 minutes. Remove the pie weights and foil and continue to bake until the shell is golden brown, about 4 to 7 minutes. Transfer the pie crust to a wire rack and set aside. Immediately start on the pumpkin pie filling. (You can also start cooking the filling while your crust is baking.) Your pie crust must still be warm when the pumpkin filling is added.

PIE FILLING

1. Adjust an oven rack to the lowest position and place a rimmed baking sheet on top of the rack. Bring oven temperature down to 400 degrees. In a large bowl, whisk together the cream, milk, eggs, egg yolks, and vanilla. In a large saucepan, bring pumpkin, yams, sugar, maple syrup, ginger, salt, cinnamon and nutmeg to a simmer over medium heat; constantly stirring and mashing the yams until thick and shiny, about 15 to 20 minutes.
2. Turn off the heat and whisk in the cream mixture until combined. Strain mixture through a fine mesh strainer. Use the back of a spoon or small rubber spatula to help push solids through the strainer. Give the mixture a whisk by hand and pour into the warm prebaked pie crust.
3. Place pie on the heated baking sheet and bake for 10 minutes. Then, reduce the oven temperature to 300 degrees and continue to bake until the edges of the pie are set and the center registers 175 degrees, about 20 to 35 minutes. Set pie on a wire rack and let cool to room temperature, about 4 hours before serving. Serve with homemade whipped cream and a sprinkle of pumpkin pie spice.
