Kudampuli vs Tamarind
The short answer
Sold as "Malabar tamarind" and called "pot tamarind" in Malayalam, and not a tamarind at all. Tamarind is the pulp of a legume pod: sweet-sour, sticky, and it thickens and browns a sauce. Kudampuli is a smoke-dried Garcinia rind: sharper, cleaner, smoky, and it leaves a curry thin and clear. Both sour South Indian fish curries, and they mark a regional line — tamarind for the Tamil curry, kudampuli for the Keralan one. Swapping one for the other changes which coast the dish comes from.
Side by side
| Kudampuli | Tamarind | |
|---|---|---|
| Botanical identity | Garcinia gummi-gutta (L.) N.Robson | Tamarindus indica L. |
| Part used | fruit | pod, fruit |
| Origin | Native to the Western Ghats of southwestern India and to Sri Lanka. | Tropical Africa, despite the species name and despite India being where the fruit became culinarily central. It was carried to South Asia early enough that its arrival is not recorded, and to the Americas by the Atlantic trade. |
| Flavour notes | sour, smoky, astringent, sharp | sour, sweet, fruity, bitter |
| Heat | Scoville does not apply | Scoville does not apply |
| Flavour | Strongly sour and slightly astringent, cleaner and sharper than tamarind and less fruity than kokum, with smoke running through it. | Sharply sour with a real fruity sweetness behind it and a faint bitterness at the end. The combination is what makes it hard to replace: most souring agents deliver acidity alone, and tamarind delivers acidity attached to a dark, raisin-and-molasses body that reads as depth rather than as sharpness. |
| Aroma | Smoky and sour, with a faint fruitiness under the smoke. | Fruity and slightly winey, with a dried-date sweetness and a distinct sour edge. Much less volatile than an aromatic spice — tamarind announces itself on the tongue rather than in the air. |
Can you swap them?
Substitution is directional: the answer is often different in each direction, and both are recorded.
Tamarind
AcceptableSours the curry, and changes it: tamarind is sweeter and fruitier, browns the sauce and thickens it. The result is closer to a Tamil fish curry than to a Keralan one.

Works for
- Fish and prawn curries when neither Garcinia is available
Does not work for
- Fish ambul thiyal, which depends on goraka’s sharp acid and dryness
- Keralan red fish curry, whose clear red sauce tamarind muddies
Cuisine: Moves the dish from the Kerala and Sri Lanka coast towards Tamil Nadu, where tamarind is the default souring agent.
Which should you buy?

Tamarind
Buy the seedless block if you cook with tamarind regularly. It is inexpensive, it keeps for a year or more, it tastes better than concentrate, and the twenty minutes of soaking and sieving can be done once for a month if you freeze the strained water in cubes. Concentrate is worth keeping as well for the days when twenty minutes is not available — just treat it as a different ingredient and start at a quarter of the quantity. What is not worth buying is a small expensive jar of thin sweetened paste from a supermarket, which is the most costly and least useful form of all three.
