Some variations of efo riro may also include ingredients like stockfish, smoked fish, or shrimp for added flavor and texture.\n\nEfo riro is known for its rich taste, vibrant color, and nutritious profile, making it a popular dish in Nigerian cuisine. It is often served with a starchy side dish like pounded yam, fufu, or rice.
