Foolproof Double-Crust Pie Dough

1. Process 1-1⁄2 cups flour, sugar, and salt together in food processor until combined, about 5 seconds. Scatter butter and shortening over top and continue to process until incorporated and mixture begins to form uneven clumps with no remaining floury bits, about 15 seconds.
2. Scrape down bowl and redistribute dough evenly around processor blade. Sprinkle remaining 1 cup flour over dough and pulse until mixture has broken up into pieces and is evenly distributed around bowl, 4 to 6 pulses.
3. Transfer mixture to large bowl. Sprinkle vodka and ice water over mixture. Stir and press dough together, using stiff rubber spatula, until dough sticks together.
4. Divide dough into 2 even pieces. Turn each piece of dough onto sheet of plastic wrap and flatten each into 4-inch disk. Wrap each piece tightly in plastic and refrigerate for 1 hour. Before rolling dough out, let it sit on counter to soften slightly, about 10 minutes. (Dough can be wrapped tightly in plastic and refrigerated for up to 2 days or frozen for up to 1 month. If frozen, let dough thaw completely on counter before rolling it out.)

Vodka is essential to the tender texture of this crust and imparts no flavor—do not substitute water. This dough is moister than most standard pie doughs and will require lots of flour to roll out (up to 1⁄4 cup). A food processor is essential to making this dough—it cannot be made by hand.
