Edit: I think we have to see a difference between domesticated pigs, bred and raised for purpose, and their cured, seasoned, fat... and some fat hacked off a wild ibex. If you’ve ever had wild game you’ll know what I mean about gamey flavors. I can only imagine that some ice age ibex would be an acquired taste at best. Pig fat is also some of the most delicious, mild fat around, which is why it’s pigs used in that article.
