Homemade Falernum
Lime peel, clove, almond, ginger, rum. The Caribbean-spice syrup that powers the Cobra’s Fang, the Test Pilot, the Three Dots and a Dash, and most of the deeper Donn Beach catalog. Two days of work spread over a weekend; pays back every drink that calls for it for the next month.
The History
Falernum originated in Barbados in the 18th century as a cordial—a low-ABV liqueur of lime, almond, ginger, and clove. The canonical bottled version is John D. Taylor’s Velvet Falernum, but tiki bartenders have long preferred a fresher homemade syrup version that hits harder on the lime peel and the spice. Jeff Berry’s reconstructions in Sippin’ Safari and Beachbum Berry Remixed standardized the modern homemade approach, building on Donn Beach’s mid-century working formula.
Ingredients
- Zest of 9 limes (peel only—no pith)
- 14 whole cloves
- 0.5 oz blanched almonds, roughly chopped
- 0.5 tsp fresh ginger, grated
- 6 oz Wray & Nephew Overproof Rum (or other high-proof white rum)
- 14 oz rich simple syrup (or 14 oz 1:1 simple)
- 1.5 oz fresh lime juice
- Pinch of kosher salt
Directions
Day 1—the infusion.
Toast the cloves and chopped almonds in a dry skillet over medium heat for 60 to 90 seconds, until fragrant. Don’t let them burn—pull as soon as you smell them strongly.
Combine the toasted cloves, almonds, lime zest, grated ginger, and overproof rum in a clean glass jar with a tight lid.
Cover and let infuse at room temperature for 24 hours. Shake the jar a couple of times during the day.
Day 2—finishing.
Strain the infusion through a fine-mesh sieve into a clean bowl. Press the solids gently with the back of a spoon to extract everything; don’t squeeze hard or you’ll get bitterness from the lime peels.
Strain a second time through cheesecloth or a coffee filter to clear out any remaining sediment.
Combine the strained infusion with the rich simple syrup, fresh lime juice, and a pinch of salt. Stir to dissolve.
Bottle and refrigerate.
Where it goes
Drinks that need this and won’t accept a substitute well:
- Cobra’s Fang — falernum is the primary flavor.
- Test Pilot — the spiced backbone.
- Three Dots and a Dash — half-ounce in the build.
- Doctor Funk — anchoring the warm-spice register.
- Saturn and Volcano Bowl — supporting role.
The commercial alternative is John D. Taylor’s Velvet Falernum — different but excellent. The House syrup vs bottled tasting test is the right way to feel the gap.
