A Shirley Temple is typically made with ginger ale, grenadine and lime. The ginger ale is the main component of the drink, with the grenadine and lime added for additional flavor.
Fill a glass tumbler with ice and pour in ginger ale until it's about 1 inch from the top of the glass. Add a splash or two of grenadine and the juice of half a lime. Stir the drink and taste, making adjustments as necessary. Garnish the drink with a maraschino cherry and an orange slice.
Some recipes also call for lemon-lime soda or orange juice. Try substituting half the ginger ale for one or both of these liquids.
