@curiousjim The Wagyu-equivalent pork: it's the mangalica pork. The Spanish Serrano ham is made from mangalica.
The Mangalica breed originated from the bakonyi breed, which was a Hungarian breed that was exported to England up to the XVIIth century. The word "bacon" comes from this now exctinct breed of pork (bakonyi -> bacon). That tells us it was the real deal... ; )
