Rum and fire. They go together like peanut butter and chocolate, or burgers and fries. But I’m here to tell you to stop lighting your rum on fire. Sure, if it’s taste-free 151 proof rum, go ahead. The less high proof vodka-in-disguise, the better. Just don’t expect setting your rum ablaze to make an awesome chalice of fire, practically a legal requirement for any volcano bowl at a decent Tiki bar.
Fire and Tiki are inextricably linked. Make no mistake, I love a good fire show with my Tiki libation, flames leaping toward the ceiling—it’s practically a sacred ritual of Tiki (assuming the fire codes allow). Add the BOOM factor, when a good Tiki master turns it up to eleven, summoning the flames of hell from a burning lime shell. Heads swivel all over the bar.
Just don’t for a minute think that high proof rum is the proper fuel of your flaming fantasies. Good Tiki fire springs from something very different. Something that feels almost secretive, that only wizards know
Browse through Tiki bar photos on Instagram, and it’s easy to figure out who knows the “secret”: Is it a small, blue flame barely visible in a lime shell? They’re not a member of the Tiki fire battalion. But if it’s a lively yellow flame dancing four inches high? A secret society member, for sure.
Conduct a simple experiment: put a half ounce or so of 151 proof rum into a short glass and light it on fire. The result (see above) is highly disappointing. In fact, the flame is almost invisible in daylight. The ethanol in 151 rum is a very pure fuel. It burns hot — really hot– exhibiting a blue flame, and not a particularly large one at that.
Now picture a grease fire. The flames can easily grow large and unruly–anything but a small, demure blue flame. When oil and grease burn, the result is an impressive yellow flame; the kind you want atop your Tiki masterpiece, albeit much more under control than a kitchen fire.

So if it’s not rum, what is this magic secret ingredient? The answer may surprise you. Stop for a moment before continuing on and make your best guess.
Lemon extract. Yes, lemon extract. It has three very valuable qualities for Tiki fire production:
- It’s food safe (though not particularly tasty on its own)
- It has a high alcohol content
- It has a hefty amount of oil –from lemon skins
It’s a surprise to many that lemon extract is high in alcohol. In fact, it’s higher in proof than your 151 rum, up to 85 percent, or 170 proof. But what makes it far better than 151 as Tiki fuel is all that oil, which creates fabulous yellow flame.
The downside to lemon extract is that it’s expensive– at least if you’re buying it two ounces at a time for $5 at the local market. Don’t do that! Smart Tiki bars buy it a quart or more at a time for around a dollar an ounce or less.
Secret ingredient in hand, how do you create the perfect flame? Typically Tiki fire masters ream the pulp out a half of a lemon or lime shell, so that it’s relatively dry. But a good flame isn’t just pouring in a slug of lemon extract– you want something to act as wick. Some bartenders swear by a sugar cube. Others prefer cubes of bread, the lighter and airier the better. And go big with the bread cube, don’t be shy!
Position the bread or sugar cube inside the citrus shell and soak it with a healthy pour of lemon extract. Tuck the shell safely and sturdily on top of the glass or volcano bowl, and find your means of ignition. I typically use a long handled butane BBQ lighter to keep my fingers away from the flames, but a long match would work as well.
Think it’s the bread or sugar cube that’s making all the difference? Think again! To vividly show the difference the fuel makes, I created two identical testbeds, each the ideal conditions for a firepot: A lime shell and bread. I soaked one chunk of bread in 0.5 oz of lemon extract, the other with 0.5 oz of 151 proof rum. The results speak for themselves:
While a raging Tiki fire in a lime shell is always a great show, true Tiki wizards like Jason Alexander and Justin Wojslaw know how to bring it to a crescendo with a blast of flames reaching practically to the ceiling. Justin in particular appears (to the naked eye) to put his hand into the flame and summon a raging Pele from it.
The reality is much more prosaic: cinnamon powder. Grab a healthy pinch, and then slowly release it above the flame—the tiny ground cinnamon particles flare briefly and sparkle like a thing of awe-inspiring beauty, as you can see in this slow motion video:
The exact origins of the first use of lemon extract for Tiki fire may be lost to history. However, after I first published this post, Martin Cate messaged me some great additional context about its recent history:
“I discovered the flaming lemon extract crouton at the now-departed Bahooka in Rosemead, CA and brought it first to Forbidden Island and then Smuggler’s which is where everyone else learned how to do this. “
Before finishing, I’d be remiss to not include the obligatory warning: Safety first. Don’t do this around highly flammable materials (say, a thatched Tiki-style roof). Have a fire extinguisher handy. All that jazz. You’ve been warned.
The current resurgence in Tiki drinks has brought the benefits of craft cocktail methodologies. We now expect fresh juices, quality rums, and artful presentation. So if you’re going all out and including fire in your cocktails, do it the right way. Use the right ingredients, and don’t set your rum on fire.
