The Singapore Sling was created by Ngiam Tong Boon at the Raffles Hotel. There are several recipes for this drink that have been adapted from the original, so do not be surprised if you see some that call for pineapple juice, powdered sugar, etc.
1.5 oz. gin
1/2 oz. cherry brandy
Few drops of Benedictine
1 oz. fresh lemon juice
Soda water
Mix ingredients in cocktail shaker with ice. Strain into iced highball. Fill the glass with soda water and garnish with a lemon slice.
* Some recipes call for a Maraschino cherry garnish and floating the cherry brandy instead of mixing it.
