Grilling pork chops is an entirely different experience than grilling red meat. While steaks can be charred on the outside and a delicious shade of pink or red inside, pork needs to be more uniformly cooked throughout. Therefore, use a medium direct heat while grilling pork so the inside cooks evenly with the outside.
