Two thousand years old and still edible. And they know because they’ve tried it. Bravery.
That’s some aged cheese.....

About 1/3 of the “bog butter” finds are actually meat of some sort (no idea what kind, no one knows), perhaps starting out as lard. These “bog butter” finds are also found in Scotland, so the animal matter in those are probably haggis that someone buried and claimed they’d finished every bite.
