Kiri Smoke: Why We Cold-Smoked Ratanakiri Pepper for Four Hours – Piper

Smoked pepper already exists. It just isn't very popular, and most of what we've tried wasn't worth eating.

We've tasted a lot of it. Sourcing trips through Cambodia, parts of Vietnam, and around Southeast Asia... anywhere pepper grows, someone has eventually tried putting it over a fire. What we found is that not all smoked peppers are created equal. Not remotely.

Smoke can be a bully when used improperly. Put a peppercorn over a fire without thinking very hard and the first thing you lose is exactly the part you paid for: the aromatics, the lift, the character that made that pepper worth sourcing in the first place.

However, when done with finesse, it's remarkable. The smoke becomes a second layer instead of a blanket.

So we decided to make one worth eating which left us two questions nobody could answer for us:
1) which pepper deserves to be smoked, and 2) for how long?

Looking for a terroir that could take smoke

Kampot was never on the table.

Debut Blend is a bouquet. Floral, citrusy, herbaceous, with a lift that arrives before the heat does. Those aromatics are volatile - the first thing to leave, and the entire reason anyone pays for Kampot. Put it over a fire and you don't get smoked Kampot... you get smoke, and a faint memory of what used to be underneath.

So we needed a different pepper. Hotter. Bolder. Structured enough to take four hours over a fire and gain a layer instead of losing one.

We found it in the middle of an afternoon with a fellow pepper lover who tastes by the handful, five or ten corns straight out of his palm, the way you'd eat almonds. Somewhere in that conversation, Ratanakiri came up.

It sits in the mountains of northeast Cambodia, a long way from the Kampot coast. Deep red volcanic soil, cooler highland nights, and a year that splits hard between heavy monsoon and a long dry season that concentrates everything. You can taste all of it: the pepper comes out denser, with a bite that keeps arriving after you'd expect it to stop.

Not better than Kampot... better suited. This distinction turned out to be the entire project.

Coconut husks, a long tube, and 35°C

Then the second question. How much smoke is the right amount of smoke?

We ran it at two hours, at three, three and a half, and at four - we tasted our way through a ton of samples. 2h ended up being too polite. You could tell something had happened, but it didn't commit. 3-3.5h was getting closer but we felt like when ground, it still didn't have enough oomph. 4h was the one.

The target was oddly specific: when you tear open a Kiri Smoke refill, you should get a real whiff of smoke before you've ground a single peppercorn. That's the moment we were chasing. But push past it and you've made a smoke product with pepper in it, and the peppercorn underneath vanishes completely. That's the mistake we kept tasting everywhere else.

Four hours gives it enough depth without the wreckage. Three would have been safe... but safe wasn't the point.

The method matters as much as the clock. We cold smoke using dried coconut husks that would otherwise be thrown away, and the smoke doesn't go straight into the chamber. It runs down a long tube first, and by the time it arrives it has cooled to around 35°C. Then it sits sealed in with the peppercorns and infuses.

No direct heat. Nothing cooking. Just time, cool smoke, and a closed box. That's why these come out with their oils intact instead of baked off. It's slow, it's fussy, and it's the only way this works.

What it tastes like

Smoke. Wood. Eucalyptus. Roasted cocoa.

Smoke-forward and woodsy, lifted by a cool eucalyptus note and finished with roasted cocoa. The heat builds slowly instead of arriving all at once, with a campfire depth that lingers long after the grind.

Personally, what I love most is that it happens in stages. Take one whole Kiri Smoke peppercorn and put it in your mouth with a piece of good cheese. The aroma hits first, immediately. Then over the next ten seconds the heat starts ramping and slowly coats your whole mouth.

We sent a box to a loyal Piper customer to try out a few months ago and here's what he had to say:

One peppercorn and a full smokey arc. It's one of my favourite party tricks and its derailed more than one dinner conversation :)

Where to point it

Coarse over fatty meats. Steak, lamb, pork belly. The smoke and the heat cut straight through the richness.

Fine into marinades and dry rubs, so the smoke works all the way through instead of sitting on top.

Medium-coarse to finish roasted mushrooms, grilled vegetables, or anything creamy, for a low embers note underneath.

Where it doesn't belong is anywhere Kampot already wins. This is not a Debut Blend replacement. Debut Blend is still what goes on eggs in the morning, on fish, on anything where you want the pepper to sing rather than shout. Kiri Smoke is for the rich, fatty, smoky half of your cooking.

Two peppercorns with two different jobs.

We only made 50kg

Kiri Smoke started as a small batch. Fifty kilograms, one region, one four-hour smoke, packed in Singapore into 20g refills for your Piper, five to a box.

We made it small on purpose. We wanted to know whether you'd love this the way we do before we went further, and the honest answer is that we didn't know. Now we'd like to find out.

If it lands, Ratanakiri has a lot more to give us... and there are still 4,000+ pepper varieties out there in the world we haven't touched.
