Combine the honey and the minced black truffle in a mason jar or another airtight container. Label, date, and refrigerate or freeze until needed.
Notes
You need to keep this cold to preserve the truffle's aroma. Even so, after a week in the fridge it will lose some of it's potency, so for long term storage you can freeze it, preferably in a plastic container. It goes without saying the truffles need to be as fresh as possible for the best result.
