Anchovies: Anchovies are small saltwater fish of the herring family. Rarely eaten fresh, they are usually sold in cans or jars and are used as a seasoning. Anchovies are a classic ingredient in salade NiÃ§oise and Caesar salad, and are also a popular pizza topping. The tiny fillets are heavily salted and packed in oil.
