Notes
Use diet soda. Feel free to use diet ginger ale or diet lemon-lime soda. You could even use club soda for a lighter cocktail.Make it non-alcoholic. The Shirley Temple is a classic mocktail. Jump over to this recipe to make a virgin Shirley Temple for the kids and non-drinkers instead.Mix up a Dirty Shirley Black. Add an ounce of dark rum into the mix for a darker variation of this cocktail.Make a Roy Rogers. Use cola instead of ginger ale or lemon-lime soda. Make it a float. Make the Shirley Temple in a pint glass, and fill it ¾-full. Add a scoop of vanilla ice cream on top.
