One of my favorite archaeology stories comes from a Reddit AMA waaay back over a decade ago, there was this girl who was on an archaeological expedition somewhere in the Middle East and they had unearthed a bunch of ancient honey jars. Honey, famously, never goes bad, and their professor said that if anyone wanted to try some, they could. Most didn't, but she did- lo and behold, tasted very much like normal honey.

Months later when they were back in the states they had performed some tests on the honey and realized that these jars had originally contained stillborn fetuses, a now known practice, which had dissolved into the honey over the millennia. So she had eaten human fetus honey.

I know it sounds made up but she was a legit archaeologist and could back it up with names and dates and shit, though I'm hazy on the details.
