Add a tropical twist to your sweet and sour pork ribs with this pineapple version. The ribs are marinated in a sauce made from pineapple juice, vinegar, brown sugar, and soy sauce. The pineapple juice adds a natural sweetness and tanginess to the dish. The ribs can be grilled or baked until tender and caramelized. Serve them with pineapple chunks and steamed rice for a deliciously fruity meal.
