Deep-Dish Maple-Bourbon Cream Pie

Preheat oven to 350 °F. Toast pecans on a rimmed baking sheet, tossing once, until fragrant and slightly darkened, about 10 minutes; let cool. Pulse pecans and 1 Tbsp. flour in a food processor until finely ground. Add granulated sugar, salt, cinnamon, and remaining 1 cup plus 7 Tbsp. flour and pulse to combine. With the machine running, add butter, vinegar, and 2 Tbsp. cold water in a slow, steady stream and mix just until incorporated. Transfer mixture to a large bowl and press with your hands until a dough forms. Form into a 6" disc, then transfer to pie plate and press into bottom and up sides with a flat-bottomed measuring cup. Crimp edge with a floured fork, if desired, and freeze while you prepare the filling.
