Doctor Funk
The Doctor Funk is the only drink in the tiki canon named after a real physician. Dr Bernard Funk practised in Samoa in the late nineteenth century, where his patients included Robert Louis Stevenson, and his standing prescription against the tropical heat was a mix of absinthe, lime and soda water. It was medicine by the standards of the day, and better company than most of it. When Don the Beachcomber opened his Hollywood bar in 1934 he added rum and grenadine to the doctor’s formula and put it on his first menu, which makes the Doctor Funk older than the word tiki itself: a genuine South Seas artefact smuggled into a genre that otherwise invented its own mythology. The absinthe is the drink; everything else is the delivery system. Lime and lemon keep it honest, grenadine tints it rather than sweetens it, and the soda stretches it into a long, dry, faintly mysterious cooler that drinks nothing like its neighbours on the menu.
Glassware: Collins Glass
Garnish: Lime Wheel
Ingredients
60ml
The body Don the Beachcomber added to the doctor’s medicine: clean and crisp so the absinthe stays the lead.
22.5ml
The prescription's original citrus, straight from Dr Funk's Samoan surgery. It is sharp and faintly bitter, which is exactly the right partner for anise, and it carries the drink's character.
15ml
A second, brighter acid that keeps the long build from flattening once the soda has diluted everything. The split is a period habit rather than a modern flourish.
10ml
Ten millilitres of real pomegranate for colour and dark fruit, tinting rather than sweetening. The neon syrup is a different, lesser drink.
7.5ml
The drink itself: everything else is delivery. At 7.5ml it is a spine; freehanded it becomes a licorice bath.
10ml
A small correction that lets the absinthe and the citrus meet without a wince. Ten millilitres is a seasoning measure; this is not a drink that wants sweetening.
60ml
The stretch that honours the original prescription, since Dr Funk served his absinthe long. Sixty millilitres turns a short sour into a genuinely sessionable cooler.
Instructions
Add the rum, lime juice, lemon juice, grenadine, absinthe and simple syrup to a shaker with ice.
Shake for 10 to 12 seconds.
Strain into a collins glass filled with fresh ice.
Top with the soda water and stir once to lift.
Garnish with the lime wheel and serve.
Expert Tip
Measure the absinthe honestly. At 7.5ml it is the drink's spine and the reason it tastes of anything; freehanded it becomes a liquorice bath that no amount of soda will rescue. Absinthe at 60 to 70% is one of the loudest things behind any bar, and this recipe is calibrated to a small, exact dose. Use real grenadine. Ten millilitres of pomegranate syrup colours the glass and adds a dark fruit note; the fluorescent commercial version replaces that with cherry sweets, and in a drink this dry the substitution is audible from the first sip. Shake everything except the soda, then top and stir once. Shaking carbonated water is pointless and messy, and a single stir is enough to lift the drink without knocking the fizz out of it.
Behind the Doctor Funk
Flavour Profile
The Origin
Dr Bernard Funk was a German physician who practised in Apia, Samoa, in the late nineteenth century. His patients included Robert Louis Stevenson, who spent his last years on the island, and the doctor's standing prescription against the heat was absinthe with lime and soda water. It was medicine by the standards of the day, which is to say it was alcohol with a rationale attached.
Don the Beachcomber picked it up when he opened in Hollywood in 1934, added rum and grenadine, and put it on his first menu. That date matters: it makes the Doctor Funk older than the word tiki and older than most of the genre's canon, and it is one of very few tiki drinks with a genuine South Seas provenance rather than an invented one.
The Absinthe
Seven and a half millilitres decides the drink. A classic verte brings herbal depth alongside the anise and tints the glass faintly green against the grenadine; a blanche is cleaner and lets the pomegranate colour through. Either stays a spine rather than a soak at that measure, and measuring honestly is the drink’s only discipline.
Grenadine Worth Using
Real grenadine is pomegranate juice and sugar, easily made at home by warming equal parts and bottling, and it colours and deepens the drink without sweetening it into the tiki mainstream. The fluorescent commercial syrup replaces that dark fruit note with cherry candy, and in a drink this dry the substitution is audible.
How to Serve It
Long, very cold and early in the evening: the Doctor Funk is an aperitif wearing a beach shirt, and its dryness is the point. Shake everything except the soda, strain over fresh ice in a collins glass, top briskly and stir once. The dark rum version adds weight for winter, but the white rum original is the drink Samoa’s doctor would still recognise.
Why Two Citrus
Lime and lemon both, at 22.5ml and 15ml, which looks like fussiness and is not.
Lime is the original prescription's citrus and it carries the drink's character: sharp, slightly bitter, and the right partner for anise. Lemon is rounder and brighter, and it does something specific in a long drink, keeping the middle of the glass from flattening once the soda has diluted everything else.
A single citrus works. All-lime makes a sharper, more austere drink; all-lemon makes a softer one that loses the connection to the original. The split is worth the extra squeeze, and it is a period habit rather than a modern flourish.
A Tiki Drink That Is Not Sweet
Almost everything else on a tiki menu is built on layered rums and fruit, and arrives sweet by design. The Doctor Funk does not, and that is what makes it useful.
There is one measure of rum, ten millilitres of syrup and ten of grenadine, against 37ml of combined citrus. Stretched with soda, the finished drink is long, dry and mostly aromatic, closer to a highball than to a Zombie and considerably easier to drink early in an evening.
That makes it the aperitif of the genre, which no other tiki drink really is. Serve it first, before the rum starts stacking up, and it does a job the rest of the menu cannot.

The Spirit
White RumWhite describes a filter rather than an age. A good deal of light rum spends time in oak and then has the colour taken back out with charcoal, which leaves the roundness that ageing gave it and none of the shade.

Zombie
The Zombie was created by Donn Beach at Don the Beachcomber in Hollywood in 1934 and became the most infamous drink in the tiki canon almost immediately. Beach kept the recipe encoded for decades, forcing rivals into inferior imitations that gave the Zombie its reputation for being more alcohol than intention, and the original was not reconstructed with confidence until Jeff Berry published Sippin' Safari in 2007. Beach called it a mender of broken dreams and limited his customers to two per sitting. Both descriptions remain accurate. The official build splits three rums across the palate rather than stacking four: Jamaican for aroma and fruit, gold Puerto Rican for body through the middle, and Demerara for smoke and weight underneath. Lime, falernum and a dash of grenadine frame them. What makes it the Zombie rather than a rum punch is Donn's Mix, which is grapefruit juice cut with cinnamon syrup, and six drops of Pernod. Both were part of the coded recipe, both were missing from every version poured between 1934 and 2007, and their absence is exactly why the drink spent seventy years with a reputation for brute strength.
Mojito
The Mojito is one of the oldest Cuban cocktails on record, its roots traced to a sixteenth-century proto-version called El Draque, named after Sir Francis Drake, whose fleet anchored off Havana in 1586. Drake’s sailors mixed local aguardiente, the rough precursor to Cuban rum, with mint, lime and sugar as a remedy for dysentery and scurvy. The combination has proved more enduring than the illness. The modern Mojito is built on white rum, with soda water extending it into a long, refreshing serve suited to the Cuban climate. Hemingway is associated with it through La Bodeguita del Medio, and whether that association is accurate or partly mythologised is debated. The drink does not need it. Technique matters here more than most high-volume bars are willing to invest in: mint pressed rather than muddled, lime squeezed fresh, sugar dissolved before the rum, and soda poured gently enough to survive into the first sip.
Three Dots and a Dash
Three Dots and a Dash was created by Donn Beach at Don the Beachcomber in 1944 and named after the Morse code signal for the letter V, the Allied symbol for victory during the Second World War. The drink was Beach’s tribute to American military service, and the garnish states the name directly: three cherries as the dots, a single pineapple chunk as the dash. The structure is a complex tiki build. Aged rum and rhum agricole as a split base give a depth and a grassy character neither could deliver alone; fresh orange and lime give a layered citrus structure; and honey syrup, falernum and Angostura supply the aromatic complexity that connects it to Beach’s wider repertoire. The rhum agricole is the defining structural choice. Produced from fresh cane juice, it brings a vegetal character entirely distinct from molasses rum, sitting at the top of the profile while the aged rum anchors the depth beneath it.
