A Gin Fizz is the best-known cocktail in the Fizz family. A Gin Fizz contains gin, lemon juice, sugar, and carbonated water, served in a highball glass with two ice cubes. The drink is similar to a Tom Collins, the difference being that a Tom Collins historically used “Old Tom Gin” (a sweetened version of, and precursor to, London Dry Gin).
Serve on the rocks, poured over ice in a highball glass.
