The Singapore Sling is a South-East Asian cocktail that was developed sometime before 1915 by Ngiam Tong Boon, a bartender working at the Long Bar in Raffles Hotel Singapore. The original recipe used gin, Cherry Heering, Bénédictine, and fresh pineapple juice, primarily from Sarawak pineapples which enhance the flavour and create a foamy top.
