Preparation -
Process the crackers or cookies in a food processor or a blender to make crumbs. Add cinnamon (if using). In a mixing bowl, combine the crumbs with the melted butter or margerine. Toss with a fork to lightly moisten all the crumbs. Spread the moistened crumbs evenly on the bottom and up the sides of a pie pan or on the bottom only of a springform pan. Press in place with your fingers. Bake at 350º for 8 to 10 minutes. Allow to cool completely on a wire rack before adding the pie filling or cheesecake filling.
