Shake gin or vodka and grapefruit juice in cocktail shaker. Strain into a highball glass.
A greyhound (or Amazone) is a cocktail consisting of grapefruit juice and gin or vodka mixed and served over ice. If the rim of the glass has been salted, the drink is instead called a salty dog.
History
Harry Craddock's Savoy Cocktail Book from 1930 describes a "grapefruit cocktail" made with gin, grapefruit jelly, and ice.[1] Craddock mentions that the cocktail is derived from similar cocktails. A recipe for a cocktail with the name "Greyhound" appears in Harper's Magazine in 1945: "The cocktails were made of gin, sugar, and canned grapefruit juice – a greyhound. This cocktail was served at Greyhound's restaurant chain, Post House, that was located at bus terminals."[1][2]
After World War II, the recipe was more commonly made with vodka instead of gin.[3][better source needed]
Some similar cocktails use grapefruit soda instead of grapefruit juice. Examples include the Finnish Lonkero (ready-to-drink mix of grapefruit soda and gin) and the Mexican Paloma (grapefruit soda and tequila).
