Known as the specialty drink of New Orleans, where it was invented in 1887 as the first beverage in the fizz family, Gin Fizz is a cocktail made with gin, Gomme syrup or sugar, lemon juice, and soda water. The cocktail is prepared by shaking gin, lemon juice, and sweet syrup with ice.
When strained in a glass, it is topped with sparkling water which provides it with a bubbly effect, hence the fizz in its name. The drink is very similar to Tom Collins, a cocktail that is traditionally made with a slightly sweeter gin called Old Tom.
