stated in the Fine Art of Mixing Drinks: "Of all the recipes published for I have never seen any two that were alike." The Times described the "original recipe" as mixing two measures of gin with one of cherry brandy and one each of orange, pineapple, and lime juice An alternative "original recipe" used gin, Cherry Heering, Bénédictine, and fresh pineapple juice, primarily from Sarawak pineapples, which enhances the flavor and creates a foamy top. The hotel's recipe was recreated based on the memories of former bartenders and written notes that they discovered regarding the original recipe.
Present style
By the 1980s, in some countries like the United States of America, the Singapore Sling was often little more than gin, bottled sweet and sour, and grenadine but showing very little relationship to the recipe used elsewhere under the same name. By that time both in Raffles Hotel, Hong Kong and generally in the UK the recipe had remained standardised as gin and cherry brandy. By 2000 one started to see the introduction of benedictine and the wider use of pineapple juice. In New Orleans, sometimes Hurricane mix was used instead of pineapple. Nowadays and internationally, unless you specify the era of the drink or your personal recipe, you have not much chance of getting anything you might recognise.
Gin slings
The gin sling, attested from 1790, described a North American drink of gin which was flavoured, sweetened and served cold. The Singapore sling has been documented as early as 1930 as a recipe in the Savoy Cocktail Book; Ingredients ¼ lemon juice, ¼ Dry Gin, ½ Cherry Brandy: "Shake well and strain into medium size glass, and fill with soda water. Add 1 lump of ice". This recipe persisted for decades and is recalled in 1982 in The Sainsbury Book of Cocktails & Party Drinks where it is also called the Singapore Sling and was the classic recipe of the time. There is a minor difference in that the measure of spirits were twice the quantity compared with the lemon and soda of the 1930 quotation and garnished with slice of lemon and a glacé cherry. There can be no doubt that these two very similar forms represent the true version of the Singapore Sling. Also documented in The Sainsbury Book of Cocktails & Party Drinks is the Straits Sling which was even stronger but also added Benedictine, Angostura Bitters, and Orange Bitters, but its garnish was both lemon and orange slices and it did not have the glacé cherry. What is sometimes served now is a transformation of the Straits Sling with orange and lemon replaced by pineapple juice as content and garnish. While some may call this a Singapore Sling, it most definitely is not so and those that serve this as a Singapore Sling risk having it rejected. Brewer's refers to the gin-sling as "a drink mainly composed of gin and lemon" and states that it has been attributed to bartender John Collins of London, "but it dates from before his time and was found in the U.S.A. by 1800" which is similar to the John Collins, another drink of gin and lemon.
