Shrimp or prawn cocktail is a seafood dish consisting of cooked prawns served in a glass with cocktail sauce. The dish has vague origins, but most people claim that it was invented by a 19th-century miner from California who first used oysters in a glass with a sauce, but the Golden Gate Hotel in Las Vegas was the first to offer a 50-cent shrimp cocktail in 1959.
It was served in a tulip glass with cocktail sauce. The cocktail sauce usually consists of ketchup and horseradish or ketchup and mayonnaise. This iconic dish was especially popular from the 1960s to the 1980s.
