So, evidently in ancient times, burying food in a peat bog was a viable method of food preservation. To that end, people had a habit of burying butter in peat bogs in order to dig it up for later consumption. Ocassionally these containers were lost and get dug up by farmers or archeologists.
Well, a couple of guys at a university decided to try their hand at actually making a few batches of the stuff, and the results were interesting.
