Crushing candy canes can be a messy job. The bits of sugary candy gets in everywhere and before you know it, coats your floor in a mess. Try placing unwrapped candy canes into a ziplock freezer bag and then a plastic grocery bag. Put the bag onto a cutting board and bash with a rolling pin until they are broken into small pieces. The pieces of candy may eventually cut throught the ziplock but will still be contained by the plastic grocery bag.
