"The Wagyu-equivalent pork: it's the mangalica pork. The Spanish Serrano ham is made from mangalica."
realworldaudio brought up an interesting bit. Read the mention of how this quality meat has different fat characteristics compared to the regular junk we eat.
I wish I could find a link to the pigs I was referring to who eat acorns. They are another Spanish raised pig used exclusively for a cured prosciutto type, cured meat. Research shows the stuff isn't artery clogging as regular meat.
