Step 1 In the bowl of a food processor, pulse the cookies, sugar and salt until sandy in texture, then add the melted butter and pulse a few more times to combine. Turn out the mixture into a buttered 9½-inch deep-dish pie plate, pressing evenly onto the sides and bottom to form a crust with uniform thickness. Freeze the crust and, just before filling and baking, run a pairing knife around the top edge to trim the cookie crust cleanly.
