Then these large fat pork chops would probably be of very little interest to you. Similar to beef steaks, the cuts depend on where they are located with the loin being the most desirable. The Birkshire chop is a marketing name for chops (similar to CAB in red meat) from pigs raised with less hormones etc. and suppose to provide a better porky taste than standard.
Bottom line given the price of pork vs. beef many restaurants are placing big fat pork chops (ala Semolina) on their menu’s because (big fat) meat eaters like me will enjoy them as much as a steak. However the profit on a big fat pork chop is 4x’s that of an equivalent steak, so that’s the true bottom line to it all.
