Cardamom NZ: Green vs Black, Pods vs Ground & How to Actually Use It

Cardamom is the third most expensive spice in the world, after saffron and vanilla. It is also the one most often used badly — wrong type, wrong form, wrong quantity, or a jar of ground cardamom that lost its aroma eighteen months ago and is now just beige dust.

This guide sorts it out: the two completely different spices both sold as "cardamom", when pods beat ground, the conversion numbers that recipes get wrong, and how to use it without your baking tasting like soap.

Green and Black Cardamom Are Not the Same Spice

This is the single most important thing to know, and it trips up a lot of people.

Green cardamom (Elettaria cardamomum, chhoti elaichi) is what most recipes mean by "cardamom". Small pale-green pods, 8 to 18 mm long, harvested before full maturity. The flavour is sweet, floral and citrusy with a cooling, almost eucalyptus edge — that cooling note comes from a compound called 1,8-cineole, and the sweet floral character from α-terpinyl acetate.

Black cardamom (Amomum subulatum, badi elaichi) is a different plant entirely. The pods are much bigger — 25 to 35 mm — dark brown, rough and wrinkled. They're harvested late and dried over open fires, which is where the smoky character comes from. It tastes camphorous, earthy and distinctly of woodsmoke.

They are both in the ginger family, and that is roughly where the similarity ends.

Do not substitute one for the other. Black cardamom in chai, kheer or a cardamom bun is a genuine disaster — smoky camphor is completely wrong against milk and sugar. Green cardamom in a slow-cooked mutton curry will simply vanish. Different tools, different jobs.

You may also see white cardamom. That's green cardamom that's been bleached for appearance, mostly for pale rice dishes. Bleaching costs it a meaningful chunk of its volatile oils, so if you use it in place of green you'll need noticeably more.

Pods, Seeds or Ground: Which to Buy

A cardamom pod is a papery three-sided capsule with the seeds sitting inside in three chambers, roughly 4 to 6 seeds per chamber. The seeds carry a sticky coating of oleoresin — that's where all the aroma lives.

The pod husk is essentially packaging, and it is very good packaging. Intact pods protect those volatile oils from air and light. The moment you grind cardamom, the oils start escaping, which is why a jar of pre-ground cardamom that's been open for a year smells of almost nothing.

Buy whole pods when

• The dish involves liquid and time — chai, biryani, pilaf, poached fruit, mulled drinks
• You want the freshest possible flavour and don't mind ten seconds with a mortar
• You use cardamom occasionally and want it to still be good in a year

Buy ground when

• You're baking, where you need it evenly dispersed through a batter or dough
• You're making spice blends in quantity
• You use it often enough to get through it in a few months
• You just don't want the faff

There's no snobbery required here. Ground cardamom is genuinely the right choice for a lot of baking — you cannot get pod-crushed cardamom evenly through a cake batter. The rule is simply to buy it in a size you'll actually finish, and store it properly.

The Conversion Numbers (And Why Recipes Disagree)

If you've ever looked this up you'll have found wildly different answers — anywhere from 6 to 10 pods per teaspoon of ground. They're not all wrong. Pod size and quality vary enormously, and a plump premium pod holds nearly twice the seed of a thin low-grade one.

Sensible working figures:

• 1 pod ≈ ⅛ to ⅝ teaspoon ground — use the higher end for large, plump, fragrant pods
• 6 to 8 pods ≈ 1 teaspoon ground
• 1 teaspoon ground ≈ 2 to 2.5 g
• 1 pod ≈ 8 to 16 seeds, depending on grade

The practical advice: start at the lower end, taste, and add more. Cardamom is very easy to overdo and impossible to take back out.

How to Actually Use It

Crushing pods

For anything simmered in liquid, you want the pods bruised, not pulverised. Press each pod under the flat of a knife or give it one light knock in a mortar until the husk splits. That's enough for the liquid to get in and the aroma to get out, while the seeds stay contained so you're not picking grit out of your chai.

For baking, go the other way: split the pods, tip the seeds out, discard the husks, and grind the seeds to a powder. Husks in a cake are unpleasantly fibrous.

Blooming in fat

For curries, biryani and pilaf, add lightly cracked pods to hot oil or ghee at the very start and give them 30 to 60 seconds before anything else goes in. The aromatic compounds in cardamom are fat-soluble, so this pulls far more flavour into the dish than adding them later. Our guide to toasting, blooming and tempering spices covers the technique in more detail.

Watch them — cardamom burns quickly and burnt cardamom is bitter and unsalvageable.

Simmering in liquid

For masala chai, kheer, rice pudding or poached pears, bruised pods go in with the liquid and simmer. Four to six pods is plenty for a pot of chai for two. Fish them out before serving, or warn people.

The overuse trap

Past a certain point cardamom stops reading as floral and starts reading as soapy, perfumed or medicinal. That threshold is lower than most people expect, particularly in baking. If a recipe calls for a teaspoon of ground cardamom in a single cake, be slightly suspicious — half is often plenty.

What to Cook With It

• ☕ Masala chai — the classic. Bruised green pods, simmered with black tea, ginger and cinnamon
• 🍚 Biryani and pilaf — whole pods bloomed in ghee with cloves, bay and cinnamon
• 🧁 Scandinavian cardamom buns — kardemummabullar. Freshly ground seeds, generously. This is cardamom's other great tradition
• 🍮 Kheer and rice puddings — cardamom with milk and rice is one of the great flavour pairings
• ☕ Coffee — a crushed pod in the grounds, Middle Eastern style
• 🍪 Baking generally — pairs beautifully with orange, rose, pistachio, coffee and dark chocolate. See our baking with spices guide
• 🧂 Garam masala — green cardamom is a backbone ingredient. Try our homemade garam masala recipe

For what else it sits well beside, our spice pairing guide is a useful starting point.

Storage

Cardamom is expensive, so it's worth storing properly.

• Whole pods: airtight container, cool dark cupboard. They hold their aroma well for a year or more. In the freezer, considerably longer.
• Ground: airtight, away from heat and light, and use it within about six months for anything like full flavour. It won't spoil after that — it just gets progressively duller.
• Never store either above the stove, next to the kettle, or in a clear jar on a sunny bench. Heat and light are what strip volatile oils.

A quick test: crush a pod between your fingers. If the smell doesn't reach you immediately, it's past its best. More on this in our guide to storing spices for maximum freshness.

Why Cardamom Costs What It Does

Cardamom pods don't ripen together on the plant. Each one has to be picked by hand at the right moment, and a single plantation gets harvested repeatedly over months. There's no mechanised shortcut. Add curing, grading and sorting — all largely manual — and you have a spice that is genuinely labour-intensive from start to finish.

It's grown mainly in India, Guatemala and Indonesia. Indian green cardamom, particularly from the Western Ghats, is generally regarded as the benchmark for aroma.

So yes, it's dear. But you use it in small quantities, and the difference between fresh, fragrant cardamom and tired supermarket cardamom is not subtle.

Frequently Asked Questions

Where can I buy cardamom in NZ?

SpiceBloom stocks both organic green whole cardamom pods and organic ground cardamom, in 50 g through to 1 kg, packed in Auckland and shipped nationwide.

Can I use ground cardamom instead of pods?

Yes, at roughly ⅛ to ⅝ teaspoon per pod. It works best where you want the flavour dispersed — batters, doughs, blends. For chai or biryani, whole pods give a cleaner, more aromatic result.

Do I need to remove the husks?

For anything simmered and strained, no — leave the pods whole and bruised. For baking, yes: use the seeds only, as the husks stay fibrous.

Why does my cardamom taste soapy?

Almost always too much. Cardamom's floral compounds tip into perfume territory quickly. Halve the quantity next time. It can also happen if you've used black cardamom where green was intended.

Is green cardamom the same as elaichi?

Yes — chhoti elaichi is green cardamom. Badi elaichi is black cardamom. If an Indian recipe just says elaichi, it almost always means green.

How many pods for a pot of chai?

Four to six bruised pods for two cups is a good starting point, alongside your ginger, cinnamon and cloves.

What can I substitute for cardamom?

Nothing matches it, but in sweet recipes a smaller amount of cinnamon or ground ginger will do at a pinch — roughly half the quantity, as both are more assertive. In savoury dishes, toasted coriander seed shares some of the citrus character. Our spice substitutes guide has more options.

Should I buy the biggest bag?

Only if you'll use it. Whole pods keep well, so a larger size makes sense there. Ground cardamom fades — buy a size you'll finish in six months.
