The national dish of Peru is ceviche, a popular seafood dish made from fresh, raw fish marinated in citrus juices, primarily lime or lemon. The marinade "cooks" the fish, giving it a firm texture while preserving its flavor. Traditionally, ceviche includes ingredients like onions, cilantro, and chili peppers, adding a refreshing and spicy kick. It's often served with side dishes such as sweet potatoes, corn, or avocado. Ceviche reflects Peru's rich maritime culture and is celebrated for its fresh, vibrant taste, often enjoyed as an appetizer or light meal, especially in coastal regions.
