Fish is one of the best ingredients to cook with. Its flavour is subtle and requires little effort or preparation to bring out. Ceviche, a dish of raw/marinated fish and seafood from the Americas, is a perfect example of this approach. Fresh fish, marinated in citrus juice and other seasonings, served simple and unadorned. Because it can be prepared in advance and its flavours are vibrant and fresh, it makes the perfect appetiser for a dinner party.
