The best of pork meat comes from loin area. Loin is the area from the head to the tail. The innermost part of the loin is best as there is less connective tissue. Although, any pork in retail can be called pork chop but there is vast difference between the different parts of the loin region itself. The center cut boneless pork chops are the best as that is the tendermost part of the pork. For example, portions near the head or shoulder would be termed blade chops. These chops have lot of connective tissue and they do not break on cooking. So there is tough or 'rubber' part which is hard to chew and intake. But the center part is the best forgourment pork serving.
On the far end is the pork loin or the tail end. They are called sirloin chops and have same characteristics as the shoulder chops. It is not that they are not delicious. They have their own and unique taste but the are not advisable for grilled pork chops. The most delicious part of the pork is the centremost portion of the pork. These are pure meat without much tissue and are away from both the head and the tail. If you are interested in a great centre chop then you must go for the T-bone shape part. On one side of the T-bone is the tenderloin and on other, the pork loin. The centre cut pork loin is the best as it involves only one muscle and there is very less fat tissue.
