Prairie oyster

A prairie oyster (sometimes also prairie cocktail), a traditional beverage, consists of a raw egg (often yolk alone), Worcestershire sauce, vinegar and/or hot sauce, table salt, and ground black pepper. A small amount of tomato juice is sometimes added, reminiscent of a Bloody Mary. Occasionally a spirit such as brandy, vodka, or gin is also included, transforming the drink into a hair of the dog. The egg is broken into a glass so as not to break the yolk. The mixture is quickly swallowed.

The unbroken yolk gives the drink a texture similar to that of an oyster. An early account from 1859 associates the recipe with the prairies of "the Plains" and with "the Rocky Mountains" of western North America.

This mixture has a reputation as a classic traditional remedy for hangovers, and has featured in media for many years.
