Kudampuli vs Kokum
The short answer
Two Garcinia rinds that do the same job on the same coast and are sold under each other’s names. Kokum, Garcinia indica, is sun-dried, purple and gently fruity, and turns a curry pink. Kudampuli, G. gummi-gutta, is smoked over a fire until black and leathery; it is sharper, and the smoke is part of the flavour of the Keralan fish curry it defines. Either will sour a coconut or fish curry cleanly without splitting it, which is why they substitute well. The difference that matters is the smoke: a Keralan meen curry without it is correct in acid and missing a layer.
Side by side
| Kudampuli | Kokum | |
|---|---|---|
| Botanical identity | Garcinia gummi-gutta (L.) N.Robson | Garcinia indica (Thouars) Choisy |
| Part used | fruit | fruit |
| Origin | Native to the Western Ghats of southwestern India and to Sri Lanka. | The Western Ghats of India, where the tree is endemic and where essentially all production remains. It is one of the few spices in this catalogue that never spread beyond its region of origin as a crop. |
| Flavour notes | sour, smoky, astringent, sharp | sour, faintly sweet, astringent, saline |
| Heat | Scoville does not apply | Not established |
| Flavour | Strongly sour and slightly astringent, cleaner and sharper than tamarind and less fruity than kokum, with smoke running through it. | Cleanly sour with a mild sweetness behind it and a light astringency that grips the back of the palate. Less aggressive than tamarind and less sharp than lime, and much of the retail material is salted, so it arrives salty-sour rather than purely sour. |
| Aroma | Smoky and sour, with a faint fruitiness under the smoke. | Faint, slightly fruity and a little fermented, closer to a dried plum or a sour cherry than to citrus. Like anardana this is a quiet spice in the jar and an assertive one in the pot. |
Can you swap them?
Substitution is directional: the answer is often different in each direction, and both are recorded.
Kokum
Good matchUse: ~1× by weight — Similar quantity by weight; taste as it simmers, as kokum is a little milder.
The same genus and the same job: a clean, heat-stable sourness that suits coconut and fish. The curry loses the smoky note and may turn slightly pink, and the flavour is a little fruitier.

Which should you buy?
Kudampuli
—
Kokum
Buy the rind. The argument here is about control rather than freshness, which makes it different from most whole-versus-ground cases in this catalogue. Kokum is dosed by adding pieces, tasting, and lifting them out when the sourness is right — an unusually forgiving way to season, and one the powder makes impossible, since it disperses on contact and commits the dish. The rind also keeps two to three times as long, and its quality is legible in a way powder is not: thickness, suppleness and the pink it throws into water can all be checked, and none of them survives milling. Powder earns its place in drinks made in quantity, and almost nowhere else.
