The Singapore Sling cocktail is unfortunately not one of the cocktails whose origin is known with certainty, but there are a few theories including the following...
Some say that this cocktail was created around 1915 at the Long Bar of the Raffles Hotel in Singapore by bartender Mr. Tong Boon Ngiam, but...
The recipe first appears as "Straits Sling" in 1922 in Robert Vermeire's "Cocktails and How to Mix Them". In this version by Robert Vermeire, the cocktail has no cointreau, pineapple juice, or grenadine syrup, but contains 2 bitters and is topped off with soda.
Ted Haigh, aka Dr Cocktail, has done extensive research on the origin of the Singapore Sling and says not even the Raffles Hotel has the original recipe. The current recipe dates from 1970 and was developed by Ngiam Tong Boon's nephew.
Still, a century later, the cocktail has become a great icon in the hotel and in Singapore where a meal without a "Singapore Sling" would almost leave a taste of unfinished business and dishonour. At the Originally, the cocktail was more intended for women, its alcoholic ingredients being well forgotten under a soft pink color.
Fairly complex in composition, the Singapore Sling cocktail is lengthened here to 20cl to precisely maintain the balance of ingredients.
A bit complex, the Singapore Sling recipe is also known in a very simplified version in which we only keep the gin (3cl), the cherry liqueur (3cl), the lemon juice (1cl) and sparkling water (5cl).
