For a tropical twist, try these pineapple sweet and sour pork ribs. The ribs are marinated in a sauce made with pineapple juice, vinegar, brown sugar, and soy sauce. The pineapple adds a tangy and sweet flavor to the ribs. Using a food processor to blend the marinade ensures that the flavors are well combined. The ribs are then cooked until they are tender and caramelized. Serve them with a side of pineapple chunks for an extra burst of tropical flavor.
