Prairie oyster

A prairie oyster (sometimes also prairie cocktail) is a traditional beverage consisting of a raw egg (often yolk alone), Worcestershire sauce, vinegar and/or hot sauce, table salt, and ground black pepper.

Occasionally a spirit such as brandy, vodka, or gin is also included, transforming the drink into a hair of the dog.

The concoction has been referred to as a traditional cure for hangovers, and has appeared in media for decades.

[2][3] However, there is no reliable evidence showing that consuming foods with this amino acid relieves hangover symptoms.

[4] It has also been suggested that a prairie oyster may seem to relieve hangover symptoms by acting as a distraction and a placebo.
