Ceviche is a refreshing and tangy seafood dish that is popular in Panama. It is made by marinating raw fish or shrimp in lime or lemon juice, which effectively 'cooks' the seafood. The ceviche is then mixed with onions, tomatoes, cilantro, and sometimes avocado. The acidity of the citrus juice gives the ceviche a bright and zesty flavor. It is typically served as an appetizer or a light lunch, and it pairs well with crispy tortilla chips or toasted bread.
