So my husband had a colleague give him a cooler still sealed from Italy with 3 black truffles in it. We were excited until we opened it and the ice packs had long warmed, the truffles were slimy, and the stench - I can only compare it to rotting fish - was overwhelming. Now I've had dishes with truffles in or on them countless times in Italy and the US and it has never smelled anything like these things smell. Has anyone else ever encountered this? Will they mellow with cooking? Should we even use them? We have them in the fridge sealed in a container with rice.
