Basic Cheesecake Crust

Mix the graham crackers and sugar, then add butter and mix with a fork
until completely moistened. Press mixture into the bottom and up 1/3rd of
the side of a 9-inch springform pan. Refrigerate for 1 hour.

Variations: Use ginger snaps instead of graham crackers for a spicier
crust or for cakes like pumpkin. Use chocolate wafers instead of graham
crackers for a chocolate, white chocolate, or certain fruit-flavored or
~topped cheesecakes like raspberry, cherry, or orange. For a sweeter,
moister crust (do this only if the cheesecake is going to get eaten
quickly, because it gets mushy faster) use brown sugar instead of white.
