For a flavorful twist, try these five-spice sweet and sour pork ribs. The ribs are marinated in a sauce made with five-spice powder, vinegar, sugar, and soy sauce. The five-spice powder adds a complex and aromatic flavor to the ribs. Using a food processor to blend the marinade helps to distribute the spices evenly. The ribs are then cooked until they are tender and caramelized. Serve them with a sprinkle of chopped cilantro for added freshness.
