Coat an 8 or 9 inch pie pan with 1 teaspoon peanut oil, sprinkle with 1/2 cup macaroon crumbs. Chill.

Spread 1 tablespoons soft butter over an 8 or 9 inch pie pan. Sprinkle over this surface 1/2 cup graham cracker crumbs mixed with 1/2 teaspoon cinnamon and 1 tablespoon sugar. Chill.

Other crumbs may be used, such as whole wheat flakes, corn flakes, vanilla, ginger, or chocolate wafers, rusks, zweiback, etc. The small amount of peanut oil or butter keeps the calories down.

A crumb crust can also be baked to bind it together instead of chilling. This takes 5-7 minutes at 375 degrees. But in this case, no chilling period is necessary, and the filling, made while the crust is in the oven, can be put immediately into the shell.
