Rudderfish ceviche is a refreshing and tangy seafood dish that originates from Latin America. This ceviche is made with fresh rudderfish fillets, which are marinated in a zesty mixture of lime juice, cilantro, red onion, and jalapeno. The acidity of the lime juice 'cooks' the fish, resulting in a tender and flavorful dish. Serve the rudderfish ceviche with tortilla chips or as a topping for tostadas for a light and delicious appetizer or main course.
