A porterhouse pork chop is a bone-in pork chop with the pork loin on one side of the T-bone and the pork tenderloin on the other.

It's dark, rosy, pink and highly marbled for richer flavor and tenderness from the fat injected prep process that has to be tasted to be believed.  Its flavor is lush, distinctive, and the marbling yields unparalleled juiciness for pork.
