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. Tomato juice is sometimes added, reminiscent of a Bloody Mary. The egg is broken into a glass so as not to break the yolk. The mixture is quickly swallowed. The unbroken yolk causes the drink to bear a texture similar to that of an oyster. The concoction has been referred to as a traditional cure for hangovers, and has appeared in media for decades. Supposed hangover remedy properties 
Though considered a traditional hangover remedy, the prairie oyster has not been scientifically proven to treat hangover symptoms. Headache experts say that a prairie oyster will not work as a remedy for a hangover. It has been suggested that the raw egg in a prairie oyster may alleviate the symptoms of a hangover since eggs contain cysteine, an amino acid which helps the body break down acetaldehyde, a by-product of processing alcohol. However, there is no reliable evidence showing that consuming foods with this amino acid relieves hangover symptoms. It has also been suggested that a prairie oyster may seem to relieve hangover symptoms by acting as a distraction and a placebo. In popular culture 
The prairie oyster has appeared in popular media since the early 20th century. Notable appearances include:
In James Joyce's novel "Ulysses", a prairie oyster is mentioned in passing in episode 14. In P. G. Wodehouse's 1916 short story "Jeeves Takes Charge", Jeeves cures Bertie Wooster's hangover with his version of a prairie oyster. The drink is not named in the story but it fits the description of a prairie oyster. As Jeeves says, "It is a little preparation of my own invention. It is the Worcester Sauce that gives it its colour. The raw egg makes it nutritious. The red pepper gives it its bite." Jeeves also serves this hangover cure in other stories. It is very effective, and Bertie suspects that there is more to the drink than the ingredients mentioned by Jeeves.
