1. Crush the gingersnaps to create crumbs. You can do this by adding the gingersnaps to a food processor and pulsing until crumbs or place the gingersnaps in a plastic bag and crush using a meat mallet.
2. Divide half of the cheesecake mixture evenly between the dishes and top with the remaining graham cracker or gingersnap crumbs and then more pecans. (see the tip in the notes for a trick on filling the jars)
