Join Molly Baz and Bon Appétit Editor in Chief Adam Rapoport in the Test Kitchen as they make Pork Marbella. We took a classic Chicken Marbella recipe and made it weeknight-friendly by using quick-cooking pork tenderloin instead. The meat is marinated and then cooked in those same delicious juices, which get turned into a luscious sweet-and-sour pan sauce.
