The other day I found some lime jello on the back shelf of my refridgerator. I don't know how long it's been in there and I was wondering how to tell if it's still edible. Can't really look for mold because the mold and the jello are both green. It does'nt have any odor to it. I dont see any fuzz growing on it. Does anyne know how long jello keeps after it's been made? This jello could be 4 or 5 months old. Should I eat it or just throw it away? I really hate to waste good food. Please advise.
