How to Store Peppermint Bark

The candy in peppermint bark stores well at room temperature with a simple covering of plastic, but the "bark" in peppermint bark -- the chocolate -- doesn't last long when exposed to oxygen, light or heat. So, storing peppermint bark for maximum shelf life requires an airtight container and a dark, cold place -- in other words, a refrigerator or freezer. Wrap peppermint bark as soon as it cools if you don't use it right away.
