The main ingredient in the dish "Ceviche" is raw fish or seafood, typically marinated in citrus juices, such as lime or lemon. The acidity from the citrus not only imparts flavor but also “cooks” the fish by denaturing its proteins, giving it a firm and opaque appearance. Ceviche is traditionally seasoned with ingredients like onions, cilantro, and chili peppers, varying by regional styles. This refreshing dish originates from coastal Latin American countries, particularly Peru, where it is a cultural staple. Ceviche reflects the vibrant flavors and culinary traditions of the region.
