Which garnish is commonly found on a whiskey sour?

A whiskey sour is a classic cocktail that typically consists of whiskey, lemon juice, and sugar or simple syrup. The drink is known for its balance of sweet and sour flavors. The common garnish for a whiskey sour is a maraschino cherry, which adds a touch of sweetness and an appealing visual contrast to the drink. The cherry complements the citrus notes of the lemon juice and enhances the overall drinking experience.

While other garnishes like lemon twists or mint sprigs are used in various cocktails, they are not traditional for a whiskey sour. Mint sprigs are more often associated with drinks like mojitos or juleps, while lemon twists might be used in drinks that specifically highlight citrus, such as a whiskey lemon drop. Olives are generally reserved for savory cocktails like martinis and do not align with the flavor profile of a whiskey sour. Hence, the maraschino cherry is the appropriate and established garnish for this cocktail.
