This pork tenderloin turns out perfect every single time I make it. The citrus marinade makes the meat so tender, moist, and flavorful. But the other key to success is searing the meat before you transfer it to the oven. It locks in all the juices, so you don’t end up with dry, tough meat. I know it’s tempting, but do not skip that step! This marinade works well on pork chops, too!
