I bought this cheese thing at Trader Joe's a while back.... it's called brie fondue. The expiration date says January 18. I opened it and it had a pretty powerful smell of ammonia. I put it in the oven as the directions said... it still smells like ammonia. Now I've never had this stuff before so I don't know how it's supposed to smell. It may sound stupid, but is this brie bad? I was going to serve it to guests tonight. Should I just chuck it? Thank you so much!
