Cinnamon Syrup
Cassia bark steeped into rich demerara syrup, and the warming backbone of tiki. It is half of Don’s Mix, the pre-batched grapefruit and cinnamon blend that Don the Beachcomber used to stop his own bartenders reading his specs.
Quick Facts

Primary Flavours
Tasting Notes
Rich demerara sweetness carrying a proper cassia glow: warm, slightly woody, with a gentle heat that lingers rather than burns.
Storage & Handling
Strain into a clean bottle and refrigerate. Keep the bark out of the finished syrup or it will keep extracting and turn harsh.
Shelf Life
3 to 4 weeks refrigerated
Usage
Pair it with lime and grapefruit and you have the flavour signature of half the Don the Beachcomber canon: the Jet Pilot, the Zombie family and every drink built on his secret mixes. Use it anywhere demerara syrup works but a warmer, spicier register is wanted, from tiki sours to an autumn Old Fashioned.
Don’s Mix, Decoded
Cinnamon syrup is the quiet engine of classic tiki. Don the Beachcomber guarded his recipes by pre-batching ingredients into numbered mixes his own bartenders could not decode, and the one that surfaces most often in reconstructions was little more than cinnamon syrup and grapefruit juice. Crack that pairing and drinks like the Jet Pilot and the Zombie stop being mysteries and start being specs.
The ratio usually given is two parts grapefruit juice to one part cinnamon syrup. The name Don’s Mix belongs to the people who reconstructed his drinks decades later rather than to Don himself, who numbered his mixes precisely so they would not have names.
The Bark Matters
Cassia, the thick, rough-rolled variety sold in most supermarkets, gives the bold, sweet heat these drinks were built on. True Ceylon cinnamon is prettier and more delicate, and gets lost the moment rum and citrus arrive. Here the cheaper bark is the correct one.
Telling them apart in the jar is straightforward. Cassia is thick and hard and rolls into a single heavy curl; Ceylon is thin and papery and layers like a cigar. Cassia sticks snap, where Ceylon crumbles between the fingers.
Making It
Making it at home takes 20 minutes: two parts demerara sugar to one part water, three or four cracked cassia sticks, a gentle simmer, then an hour of steeping off the heat before straining. The result is darker, warmer and far more useful than anything sold as cinnamon syrup on a supermarket shelf.
The bark has to come out at the straining stage rather than being left in to look decorative, because it goes on extracting in the bottle and turns the syrup tannic and harsh inside a week.
Beyond Tiki
What it adds is warmth rather than sweetness, which makes it useful well outside the drinks it was invented for. A barspoon in an Old Fashioned takes the drink somewhere autumnal without tipping it into dessert. It works in a whisky sour, against apple and pear, and in anything served hot, where spice reads more strongly than it does cold. Wherever a spec calls for demerara syrup and the drink wants more character than that, this is the substitution to reach for first.
Top Tips
- Make it with cassia rather than true Ceylon cinnamon: cassia has the louder, sweeter heat that tiki recipes assume.
- Simmer gently and steep off the heat. Boiling hard extracts bitter tannin from the bark.
- Label the bottle with the date. It looks identical to plain demerara syrup and the two are not interchangeable in a spec.
Possible Substitutions
- Falernum: softer and rounder, trading cinnamon heat for lime, clove and almond
- Demerara syrup with a light dusting of ground cinnamon shaken in: a serviceable emergency stand-in
Common Questions
How do I make cinnamon syrup at home?
Simmer two parts demerara sugar with one part water until dissolved, add three or four cracked cassia sticks, then take it off the heat and steep for an hour before straining into a clean bottle. It keeps for three to four weeks in the fridge.
Should I use cassia or true cinnamon?
Cassia. It is the everyday supermarket cinnamon, and its louder, sweeter heat is what tiki recipes were written around. Delicate Ceylon cinnamon disappears the moment rum, lime and grapefruit arrive, so the cheaper bark is genuinely the right one here.
Which cocktails need cinnamon syrup?
The Jet Pilot is the headline, and it runs through the Don the Beachcomber canon wherever his spice mixes were used, including the Zombie variations. Outside tiki it works in autumn sours, in hot drinks, and in a spiced Old Fashioned.
What is Don’s Mix?
Two parts grapefruit juice to one part cinnamon syrup, batched in advance. Don the Beachcomber numbered his mixes so his own staff could not reconstruct a recipe from watching, and this one turns up in the Jet Pilot and across the Zombie family. The name is a later reconstruction rather than his.
