Singapore Sling

Classic Cocktail

A classic hotel-style gin sling built with gin, cherry brandy liqueur, orange liqueur, Bénédictine, pineapple, lime, grenadine, bitters, ice, and soda.

Method

Method & Technique

The LMA Singapore Sling is a shaken long drink finished with soda over fresh ice.

Add gin, cherry liqueur, orange liqueur, Bénédictine, pineapple juice, fresh lime juice, grenadine, and aromatic bitters to a shaker tin. Add ice and shake firmly until the drink is thoroughly chilled and the pineapple develops a light foam.

Strain into a chilled Collins or sling glass filled with fresh ice. Top slowly with chilled soda water. Give the drink one gentle lift from the bottom only if necessary; aggressive stirring will release carbonation and collapse the pineapple foam.

Leave sufficient room in the glass for the soda and natural foam. Never place soda water in the shaker.
Pineapple juice must be cold, fresh-tasting, and consistent. Shake or agitate the juice container before measuring if the juice has separated. A weak shake leaves the cocktail disconnected; excessive shaking can create more foam than the glass can contain.

The cherry component must be a proper cherry liqueur rather than red cocktail-cherry syrup. Historically, the phrase “cherry brandy” was often used for sweet cherry liqueur. Clear, unsweetened kirsch produces a fundamentally different drink.

Strain over fresh ice rather than dumping the shaker. Fresh ice gives cleaner presentation and more predictable dilution. Fine-straining is unnecessary unless the pineapple or citrus contains excessive pulp.
Finish with a compact pineapple wedge and quality cocktail cherry. Orange and cherry can also work as a cleaner house presentation.

The finished drink should reach the guest cold, lively, lightly foamed, evenly integrated, and clearly carbonated.

Guest Story

The Singapore Sling is a strong recommendation for guests who enjoy tropical cocktails, gin, pineapple, fruit-forward classics, hotel-bar history, or long drinks with more complexity than a basic highball.

A bartender can say:
“It’s Singapore’s famous gin-based hotel cocktail, layered with pineapple, lime, cherry liqueur, Bénédictine, orange liqueur, bitters, grenadine, and soda. It’s tropical and approachable, but still structured and lightly herbal.”
For a guest interested in its history:
“It is closely associated with Raffles Hotel and bartender Ngiam Tong Boon around 1915. The exact original recipe is debated, and the pineapple-heavy version developed through the drink’s later hotel tradition.”
The famous story about its pink color disguising alcohol for women may be shared as Raffles folklore, provided it is identified as a story rather than settled history.

This is a useful bridge for someone who enjoys tropical drinks but does not want coconut, frozen texture, or a rum-dominated profile. It can also introduce a gin-uncertain guest to a drink in which gin provides structure without dominating every sip.

It is not the best recommendation for someone seeking something dry, bitter, spirit-forward, very simple, low-sugar, or stirred.

For the bartender, the Singapore Sling teaches how to make numerous ingredients speak with one voice.

For the owner, it provides strong recognition and storytelling, but only if batching, ingredient freshness, garnish preparation, and the house recipe are tightly controlled.

Guest Story

Origin

Where It Came From

The Singapore Sling is one of the most famous hotel cocktails in the classic library, but its history is considerably less settled than its familiar pink appearance suggests.

The drink is inseparably associated with Raffles Hotel in Singapore and Hainanese bartender Ngiam Tong Boon. Raffles dates its creation to 1915 at the hotel’s Long Bar. Singapore’s national heritage collections also identify Ngiam as the drink’s creator while acknowledging that the precise year remains disputed; the cocktail was certainly known by 1915.

What cannot be established with the same confidence is one surviving, uncontested “original recipe.” Early printed Singapore Sling and Straits Sling formulas were generally leaner than the modern hotel drink. They combined gin with cherry brandy or cherry liqueur, citrus, soda, and—in some versions—Bénédictine and bitters. Pineapple juice, grenadine, and orange liqueur do not appear consistently across those early records.

The elaborate pineapple-driven formula now recognized around the world represents the cocktail’s later hotel tradition and evolution. That does not make it inauthentic; it makes it one important branch of a drink whose identity changed as it moved through hotels, books, tourism, and international bars.

One well-known Raffles story says Ngiam colored the drink pink so women could enjoy alcohol while appearing to drink fruit punch. It is an excellent guest story and part of the hotel’s own narrative, but LMA treats it as legend rather than proven fact. No decisive contemporary evidence has established that this was the drink’s original purpose.

For LMA service, the Singapore Sling is a structured gin-based long drink—not miscellaneous fruit punch and not historically a tiki creation, even though its modern presentation overlaps with tropical-drink service. Gin must remain visible beneath the pineapple, cherry, citrus, herbal modifiers, bitters, and carbonation.

A properly made Singapore Sling should be cold, bright, tropical, gently herbal, lightly frothy, refreshing, and recognizably gin-driven. It should not taste like sour mix, neon grenadine, medicinal cherry flavor, or pineapple juice concealing alcohol.

Deep Dive

The Singapore Sling is a cocktail for which professional authority comes from historical honesty and a disciplined house standard—not from pretending the documentary record is cleaner than it is.

LMA Service Spec
1.50 oz London Dry Gin
0.50 oz Dark Cherry Liqueur
0.25 oz Dry Orange Curaçao
0.25 oz Bénédictine
2.00 oz Unsweetened Pineapple Juice
0.50 oz Fresh Lime Juice
0.25 oz Real Grenadine
1 dash Aromatic Bitters
1.50 oz Chilled Soda Water
Compact Pineapple Wedge and Quality Cocktail Cherry

Shake every ingredient except soda with ice. Strain over fresh ice in a chilled Collins or sling glass. Add soda slowly and give one gentle lift if required. Garnish and serve immediately.

This is the LMA balanced modern Singapore Sling, not a claim to the exact 1915 recipe. It retains the recognizable modern profile while reducing the pineapple and grenadine enough for gin, cherry, herbs, citrus, and carbonation to remain distinct.

Understanding the Historical Problem
The cocktail’s name belongs to the older sling family, whose drinks were lengthened mixtures of spirit, sweetening, water, and often citrus. Early Singapore and Straits Sling records do not perfectly match one another.
A documented 1930 Straits Sling included gin, cherry brandy, Bénédictine, lemon, Angostura and orange bitters, and soda—but no pineapple or grenadine. Other early Singapore Sling formulas were simpler combinations of gin, cherry brandy, citrus, and soda.

The present Raffles formula is much more elaborate and pineapple-forward. That formula is historically important because it represents the hotel’s established modern tradition and shaped worldwide guest expectations. It should not, however, be retroactively treated as proof of every ingredient poured in 1915.
A bartender who understands this can answer both kinds of guest:
“Yes, the drink is associated with Raffles and Ngiam Tong Boon.”
“No, we cannot prove that every modern ingredient appeared in one unchanged original formula.”
That is a stronger position than repeating a neat but unsupported origin story.
Gin

London Dry gin is the LMA standard because this drink contains multiple sweet and aromatic modifiers. Juniper, citrus peel, and a dry botanical structure prevent the base spirit from disappearing.
A softer contemporary gin may produce a pleasant cocktail, but it can be overwhelmed by pineapple, cherry, and grenadine. If the house changes the gin, the completed drink—not the spirit by itself—must be tested.

Cherry Liqueur
The cherry component should contribute dark fruit, mild spice, body, and depth. It must not taste like candy, artificial almond, or cough syrup.
“Cherry brandy” in historical cocktail language commonly describes a sweet cherry liqueur rather than grape brandy merely flavored with cherry. For modern training, dark cherry liqueur is the clearer term.
Kirsch is clear, dry, and unsweetened. Substituting it without rebuilding the entire balance removes sweetness and body and does not create the same cocktail.

Bénédictine
Bénédictine supplies herbal, honeyed, and spiced complexity. At a quarter ounce, it helps the Singapore Sling rise above ordinary gin punch.
It should remain an accent. Too much makes the drink heavy and medicinal; omitting it makes the modern formula flatter and less distinctive.

Orange Liqueur
Dry orange curaçao gives a small bridge of orange peel, sweetness, and body. It connects the botanical gin to the pineapple, lime, and cherry.
The measure is intentionally restrained. The finished cocktail should not read as orange-forward.

Pineapple Juice
Pineapple is central to the recognizable modern hotel-style Sling, although it is not consistently documented in early printed Sling formulas.
Its functions are flavor, body, tropical length, and foam. More pineapple is not automatically better. A four-ounce hotel pour creates a plush, juice-forward drink; the LMA two-ounce measure produces a leaner restaurant cocktail in which the gin and modifiers remain legible.
Use unsweetened juice. If a sweetened product is used, grenadine or liqueur quantities may need adjustment. Taste the complete build before approving a substitute.

Lime
Fresh lime provides the acid structure for the LMA version. It sharpens the pineapple, controls the sugar, and gives the finish energy.
Some historical formulas use lemon, and lemon remains a defensible house variation. Lime is locked into the LMA standard because it works cleanly with the modern pineapple-driven profile. Switching citrus is a flavor decision, not a trivial substitution.

Grenadine
Grenadine should provide restrained pomegranate sweetness and a muted pink-red color. It should never turn the drink neon red or become its dominant flavor.
The appearance is a result of the recipe—not permission to keep adding syrup until a predetermined color is reached.

Bitters
Aromatic bitters provide warm spice and needed tension. One dash is sufficient. They should be shaken into the drink rather than used as a decorative float.
Orange bitters can appear in leaner historically influenced versions, particularly alongside aromatic bitters, but the LMA modern spec uses one aromatic-bitter standard for repeatability.

Soda and Carbonation
Soda reconnects the LMA build to long sling service and keeps the numerous modifiers from becoming heavy.
The soda must be cold and lively. Warm soda foams excessively and loses carbonation quickly. Add it only after the shaken portion has been strained. A slow pour down the inside of the glass helps preserve bubbles.
Current pineapple-heavy hotel formulas are sometimes served without soda. That is a legitimate modern direction. LMA retains a measured soda finish because it produces better length, lift, and drinkability for restaurant service.

Ice and Glassware
Shake with service ice and strain over fresh, solid ice in a chilled Collins or sling glass. Fresh ice improves presentation and slows uncontrolled dilution.
A hurricane glass can work, but it often encourages an oversized pour and excessive garnish. The narrower Collins or traditional sling format better supports the LMA proportions.

Garnish
Pineapple and cherry provide the most recognizable modern presentation. Both must be properly prepared and proportionate to the glass.
The garnish should announce tropical hotel service without becoming a fruit display. Orange and cherry are also defensible, particularly for a leaner house build.

Operational Standard
Because this drink contains numerous quarter-ounce ingredients, it is a sensible candidate for controlled partial batching. Gin, cherry liqueur, orange curaçao, Bénédictine, and bitters may be batched according to house policy.
Do not batch fresh lime, pineapple, soda, or garnish into a spirit mixture intended for extended storage. Fresh ingredients require separate labeling, dating, refrigeration, and daily quality checks.
The bar must publish one recipe. “Singapore Slings vary” is historical context, not permission for bartenders to improvise different proportions during service.

Recognized Recipe Directions
A bartender should understand four broad branches:
Early lean Sling: Gin, cherry component, citrus, soda, sometimes Bénédictine and bitters.
Modern Raffles-style Sling: Gin with pineapple, lime, cherry liqueur, orange liqueur, Bénédictine, grenadine, and bitters, generally rich and fruit-forward.

Tourist or high-volume Sling: Often premixed, sweet, deeply colored, and pineapple-heavy.
Craft-restaurant Sling: The recognizable modern ingredients tightened to preserve gin, acidity, herbal complexity, and carbonation.

The LMA standard belongs to the fourth branch while openly acknowledging the others.
A properly made Singapore Sling should be cold, tropical, bright, layered, gently herbal, lightly frothy, carbonated, and gin-driven. It should not be warm, flat, syrupy, neon red, medicinal, excessively foamy, pineapple-dominated, or inconsistent from bartender to bartender.
