And this is what the McRib looks like when it arrives at McDonald's frozen:
“But what IS a McRib?” you ask. Let’s let the good people at The Atlantic answer that:
This would-be rib sandwich is really a restructured pork patty pressed into the rough shape of a slab of ribs, its slathering of barbecue sauce acting as camouflage as much as coating.
“Pork” is a generous term, since the McRib has traditionally been fashioned from otherwise unmarketable pig parts like tripe, heart, and stomach, material that is not only cheap but also easier to mold and bind into a coherent, predetermined shape. McDonald’s accurately lists the patty’s primary ingredient as “boneless pork,” although even that’s a fairly strong euphemism. Presumably few of the restaurant’s patrons would line up for a Pressed McTripe.
