Which garnish is used in a Singapore Sling cocktail?

In a Singapore Sling cocktail, the traditional garnish is a flag made of an orange slice and a cherry. This garnish not only adds visual appeal but also enhances the fruity notes of the drink, which features ingredients like gin, cherry brandy, and pineapple juice. The combination of the orange and cherry provides a contrast in flavor and color, making the drink more inviting and festive. This attention to presentation is an essential aspect of mixology, particularly for classic cocktails.
