Shrimp cocktail

Prawn cocktail, also known as shrimp cocktail, is a seafood dish consisting of shelled, cooked prawns in a Marie Rose sauce or cocktail sauce, served in a glass. It was the most popular hors d'œuvre in Great Britain, as well as in the United States, from the 1960s to the late 1980s. According to the English food writer Nigel Slater, the prawn cocktail "has spent most of see-sawing from the height of fashion to the laughably passé" and is now often served with a degree of irony. The cocktail sauce is essentially ketchup and mayonnaise in Commonwealth countries, or ketchup and horseradish in the United States. Recipes may add Worcestershire sauce, hot sauce, vinegar, cayenne pepper or lemon juice. A dish of cooked seafood with a piquant sauce of some kind is of ancient origin and many varieties exist. Oyster or shrimp dishes of this kind were popular in the United States in the late nineteenth century and some sources link the serving of the dish in cocktail glasses to the ban on alcoholic drinks during the 1920s prohibition era in the United States. A version of the shrimp cocktail was popularized in Las Vegas casinos in the late 1950s (beginning with the Golden Gate Casino on Fremont Street; they sold as many as 2,000 shrimp cocktails daily, at inexpensive prices, no more than 99 cents), and is considered somewhat synonymous with the gambling and entertainment mecca.
