Which garnish is commonly used with a whiskey sour cocktail?

The garnish that is commonly used with a whiskey sour cocktail is typically a maraschino cherry and/or an orange slice. This choice not only adds visual appeal to the drink but also complements the flavor profile of the whiskey sour. The sweetness of the maraschino cherry and the citrus notes from the orange slice enhance the drink's overall taste experience, balancing the acidity of the lemon juice used in the cocktail.

In classic cocktail presentations, the inclusion of both the cherry and orange slice helps highlight the traditional roots of the whiskey sour, as these garnishes have been historically associated with the drink. They create a vibrant contrast against the dark amber color of the whiskey, making the cocktail more inviting and enhancing the overall enjoyment of the drink.
