Gin Fizz

A "fizz" is a mixed drink variation on the older sours family of cocktail. Its defining features are an acidic juice and carbonated water. It typically includes gin or rum as its alcoholic ingredient. The first printed reference to "fiz" is in the appendix to the 1876 edition of Jerry Thomas's Bartender's Guide, which contains four such recipes. The fizz became widely popular in America between 1900 and the 1940s. Known as a hometown specialty of New Orleans, the gin fizz was so popular that bars would employ teams of bartenders that would take turns shaking the drinks. Demand for fizzes went international at least as early as 1950, as evidenced by its inclusion in the French cookbook L'Art Culinaire Francais published that year. A gin fizz is the best-known cocktail in the fizz family. A gin fizz contains gin, lemon juice, and sugar, which are shaken with ice, poured into a tumbler and topped with carbonated water. The drink is similar to a Tom Collins, with a possible distinction being a Tom Collins historically used "Old Tom gin" (a slightly sweeter precursor to London Dry Gin), whereas the kind of gin historically used in a gin fizz is unknown.
