Mix all the ingredients in a highball glass with ice. Garnish with the lime wedge.
Rickeys are traditionally a dry drink, but syrup or sugar can be added. the Rickey took its name from "Colonel Joe" Rickey, a lobbyist in Washington in the late nineteenth century who regularly drank with members of Congress in shoemaker's bar. The barman who invented the drink let Colonel Joe taste it, and when the colonel called for another, he christened it the Gin Rickey. Oddly enough, Colonel Joe later became the first major importer of limes to this country. The early recipe, which first appeared in Modern Mixed Drinks, by George Kappeler, in 1900, is exactly the same as our contemporary recipe. The Gin Rickey is a jumping-off point for more of-the-moment, sexy cocktails.
