#5 Honey. I kept bees a while back. As I was clearing out my garage I found a 5 gallon bucket of honey with the date 1984 on it. I opened it up expecting to find a crystalized solid mass. To my surprise it was still liquid. It was dark, but as I recalled it was dark when I harvested it. Tasted just fine.
I believe that Archeologists found honey in the pyramids (or Egyptian tombs) and it was still fit to eat.
In my family, that forms a standing joke about aging food. “Is this celery still good to eat?” “Of course! They found celery in the pyramids, and it was still good!”
Supposedly honey does NOT go bad...EVER!
