What is the primary mixer used in a Shirley Temple?

The primary mixer used in a Shirley Temple is ginger ale. This classic non-alcoholic beverage is traditionally made by combining ginger ale with grenadine and often garnished with a maraschino cherry. Ginger ale is preferred because it adds a light, bubbly texture and a subtle spice that complements the sweetness of the grenadine.

While 7UP and Sprite are lemon-lime sodas that can sometimes be used as variations, they do not provide the same flavor profile as ginger ale. Coke is typically not associated with a Shirley Temple, as the drink is meant to be fruity and refreshing rather than rich and cola-flavored. Understanding the distinctive components of this drink highlights why ginger ale is the correct answer; it is the mixer that defines the classic recipe.
