I really don't know what happened here. This is a tin of pineapple I rescued from the back of a cupboard. Its probably a few years old. The tin label had mostly turned black. I opened it anyway and discovered all the pineapple was black too! Funnily enough it didn't smell bad. Maybe I've discovered a new fermented delicacy?
Well, I'm game to taste most things but chickened out of this one.
I thought canned foods were meant to last a long long time. Anyone know what happened?
