This variation on the fizz traces its origins to a whiskey-based drink created by Joe Rickey, a lobbyist from Missouri who moved to the nation’s capital in the late-19th century. He began requesting whiskey cocktails sans sugar from local bars. The drink was a hit and soon found nation-wide popularity, so much so that Rickey eventually got into the drinks business himself, selling soda water. This version replaces whiskey with gin, which has arguably become the drink’s most famous riff.
