How to Make It
In the bowl of a food processor fitted with a metal blade, pulse the flour, sugar, baking soda, and salt until combined. Add the butter and pulse until the dough just begins to clump together. Add the egg and vanilla and continue to process until the dough comes together into a ball. Scrape down the sides of the bowl, if necessary. Shape into a disk, cover with plastic wrap, and refrigerate at least 20 minutes or until firm. Bake the crust in a 350° F preheated oven until golden or according to your pie recipe instructions.
