Prawn cocktail or shrimp cocktail is a seafoo dish, which is usually served as a starter. It consists of cooked, peeled, chilled shrimp or prawns, leaf salad and cocktail sauce - sometimes known as sauce Marie Rose or Thousand Island Dressing - which is essentially a combination of mayonnaise and ketchup. The sauce can be served as a dipping sauce (common with larger shrimp) or as a dressing over or in the entire dish. Prawn cocktail is often served with bread. The dish was very popular in the 1960s in the UK.
