A greyhound is a cocktail made with grapefruit juice, and gin and served over ice. The beverage is called a salty dog if the rim of the glass has been salted. The earliest known mention of this cocktail is in Harry Craddock's Savoy Cocktail Book of 1930.
This classic mixed drink needs nothing more than vodka or gin and grapefruit juice. While it is not available on many bar menus, the greyhound is the recipe that all bartenders know. Optionally for the greyhound, a twist of grapefruit, lime or lemon can be used as a garnish.
Gather the ingredients.
Fill a rocks glass with ice, then add the vodka or gin and the grapefruit juice and stir gently.
Garnish with a lime wheel.
