I recently purchased a jar of black truffle salt (from Eataly in NYC), and am having a tough time with proper storage now that I have opened it. The truffle scent is so strong that I can't seem to contain it. Tupperware worked for a few days, but is no longer a good enough fortress. Has anyone had experience with storing truffle products such that they could lend me a nugget of advice before I go out on a jar-buying expedition?
Thanks in advance! (I understand this is a wonderfully high brow problem to have, it's just not one that I anticipated!)
