Pork chops are a lean cut of meat so they can get tough when overcooked. This pork chop marinade helps them retain moisture because the salt in the marinade acts as a brine which infuses flavor and moisture in the pork chops. You can also use a meat tenderizer or any acidic fruit juices like lime, lemon, or pineapple juice. The acid penetrates the meat and breaks down the protein which tenderizes the pork chops.
