If you don't want to make a caramel or fudge sauce, Nancy Silverton suggests using high-quality jarred ones like King's Cupboard cream caramel sauce (kingscupboard.com) and Scharffen Berger chocolate sauce (scharffenberger.com).
Spanish salted peanuts with skin, toasted, for serving
Preheat the oven to 325°. In a medium bowl, mix the graham cracker crumbs with the butter, cinnamon and nutmeg. Press the crumbs into a 9-inch glass or ceramic pie plate to form an even crust. Bake the crust in the center of the oven for 8 minutes, or until lightly browned. Let cool.
Let the ice cream thaw in the refrigerator for 15 minutes. Scoop the ice cream in a large bowl and, using an electric mixer, beat it just until very soft but not melted. Spread the softened ice cream into the pie shell and freeze for at least 1 1/2 hours, or until the ice cream is firm.
Cut the pie into wedges and serve with the dessert sauces and peanuts.
