Marie Rose sauce

Marie Rose sauce (known in some areas as cocktail sauce or seafood sauce) is a British condiment made from a blend of tomatoes, mayonnaise, Worcestershire sauce, lemon juice and pepper. A simpler version can be made by merely mixing tomato ketchup with mayonnaise. The sauce, as well as the dish (prawn cocktail) from which its more common name, cocktail sauce, comes, was invented in the 1960s by renowned British cook Fanny Cradock.
