Black Cardamom: The Smoky Himalayan Cardamom and How to Use It

Crack a black cardamom pod and you get smoke and camphor, nothing like the green cardamom in your chai and baking. It’s a different plant, too: Amomum subulatum, a ginger-family plant of the eastern Himalaya, sold in India as large cardamom. The smoke isn’t grown into the pod. It gets added after harvest, when the pods are traditionally dried over a wood fire. And a little goes a long way: one or two pods will flavor a big pot.

At a glance

What black cardamom is

Amomum subulatum is a perennial herb in the ginger family. It grows about 1.5–2.5 m tall, is found at 800–2,000 m elevation, and is cultivated mainly in India’s northeastern Himalayan region. It’s native from Nepal to central China and isn’t recorded as introduced anywhere.

It’s not a dark form of green cardamom. Green cardamom is Elettaria cardamomum, a separate genus native to southwest India. Stand-ins for true cardamom, the so-called false cardamoms, sometimes turn up in the trade. See black vs. green cardamom for a side-by-side comparison, and Thai cardamom for another Amomum spice.

You’ll see names like “Nepal cardamom” and “brown cardamom” all over. The sources we reviewed don’t use them; they say “large cardamom.”

Why it tastes smoky

The smoke gets added after harvest. It isn’t grown into the pod. The traditional curing process uses flame heat over pits, which is what turns the pods dark brown. A patent from India’s Central Food Technological Research Institute (CFTRI) lays out the system in more detail. Freshly harvested wet pods are spread 20–25 cm deep on a platform, firewood burns below, and smoky air passes up through the bed of capsules for two to three days, with an occasional stir. Cardamom dried this way, it says, is dark brown with a strong smoky smell from direct contact with the smoke, and the heat may change both the original aroma and the chemical makeup. The smoke carries over into oil distilled from the pods, which is why CFTRI patented a way to remove it. Most large cardamom is still dried the traditional bhatti way, according to the same source.³

Flavor and the compounds behind it

ICAR-IISR describes the flavor as strong, smoky and slightly camphoraceous, and names 1,8-cineole as the main component of its essential oil.² 1,8-Cineole smells like camphor, which fits. Under the smoke, it’s resinous and cooling, with a dry, slightly astringent finish. We couldn’t find a figure, from a source we could open, for the pods’ oil content or the share of 1,8-cineole in the oil.

Where it is grown

Its range covers Assam, Bangladesh, south-central and southeastern China, the eastern Himalaya, India, Myanmar, Nepal and Tibet. In India, Sikkim, Darjeeling and Arunachal Pradesh are the main producers.

The Spices Board of India puts large cardamom at 9,552 tonnes from 46,017 hectares in 2024-25 (final), with an advance estimate of 9,831 tonnes from 46,472 hectares for 2025-26. The three seasons before that were 8,812 t (2021-22), 9,075 t (2022-23) and 9,288 t (2023-24). The cardamom figures in that table are the Board’s own estimates and can be revised.¹ We found no official production figures for Nepal or Bhutan to compare.

Claims that black cardamom is grown commercially in Somalia, Cameroon or on the China–Vietnam border couldn’t be traced to a source.

How black cardamom is used

Large cardamom is widely used in rice dishes, curries, meat dishes and spice blends. Whole pods go into biryani and rice preparations, and the ground spice into masala blends and garam masala. Its smokiness makes it a savory spice; we found no source describing traditional sweet uses. For garam masala itself, see garam masala.

Crack whole pods and add them early to a braise, dal or pot of rice, then fish them out before serving. One or two pods will flavor a big pot. A quick toast in a dry pan before grinding sharpens their smell. You can also scrape out the seeds and grind them on their own for a less woody result.

You’ll sometimes read that black cardamom goes into some versions of Chinese five-spice powder. Britannica’s list of the five spices (fennel seeds, cassia, cloves, star anise and Sichuan pepper) doesn’t include it,⁴ and we found no source for a Chinese use of Amomum subulatum specifically.

Buying and storage

Good pods are big, intact, dark brown and strongly smoky when you crack them. That dark brown color itself comes from the flame curing. We found no grading standard or shelf-life figure from a regulator or standards body. Like other whole spices, store the pods whole, sealed and away from heat, and grind as you need them.

Health claims

Online, black cardamom gets credited with anti-inflammatory, anticancer, anti-obesity and anti-diabetic effects, and with being a rich source of potassium and fiber. We found no systematic review or regulator assessment of Amomum subulatum in people, and no nutrient data from USDA FoodData Central, so we’re not making any health claims for it. Claims about its use in traditional Chinese medicine, Ayurveda and Unani, or by ancient Arabs, Greeks and Romans, couldn’t be traced either.

Substitutes and comparisons

Green cardamom gives you the camphor and floral notes without the smoke. A little smoked paprika or a pinch of another smoky spice can cover the smoke. See black cardamom substitutes for the ranked list, black vs. green cardamom for how they differ, and cardamom for the green spice.
