Amchoor vs Tamarind
The short answer
Two South Asian souring agents from different fruits. Amchur is a dry powder of unripe mango and sours without adding moisture, sugar or colour. Tamarind is a wet pulp or paste, sour but also sweet and distinctly fruity, and darkens a dish. A recipe using tamarind for a sweet-sour balance is not satisfied by amchur, and a dry rub calling for amchur cannot take a wet paste.
Side by side
| Amchoor | Tamarind | |
|---|---|---|
| Botanical identity | Mangifera indica L. | Tamarindus indica L. |
| Part used | fruit | pod, fruit |
| Origin | South Asia, where the mango is native and where essentially all amchoor is produced. | 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, fruity, earthy | sour, sweet, fruity, bitter |
| Heat | Scoville does not apply | Scoville does not apply |
| Flavour | Sharply sour with a fruity, faintly resinous background and a slight astringency. It is more purely acidic than sumac and less sweet than tamarind, and it hits immediately rather than building. | 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 | Faintly fruity and resinous, with a sharp sour edge. Much quieter than its taste, which is unusual and worth knowing — a smell test underreports it. | 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.
Amchoor
SituationalUse: ~0.5× by volume — Roughly half the volume of prepared tamarind pulp, added late rather than early. Amchoor is a dry powder and cannot supply the body tamarind gives a sauce.
A closer flavour match than lemon and a worse structural one. Amchoor is dried green mango, and like tamarind it is sour with a fruit character behind it rather than a bare acidity — which is exactly what citrus cannot supply. What it cannot do is thicken, colour or survive a long simmer: it is a finishing powder where tamarind is a cooking ingredient.

Works for
- North Indian dishes, where amchoor already belongs
- Adjusting sourness at the end of cooking
- Dry preparations and rubs, where a wet pulp would be wrong
Does not work for
- Sambar and rasam, which need the body and the long cooking
- Pad thai and other sauces built on tamarind for texture as well as taste
- Anywhere the dark colour of tamarind matters
Cuisine: Moves a South Indian or Southeast Asian dish towards a North Indian register.
The two are the standard souring agents of neighbouring cuisines and are not interchangeable by measure or by method. Kokum and pomegranate molasses are nearer still on the sweet-sour axis and are not held in this dataset yet.
Which should you buy?
Amchoor
Powder for most people, slices if you use it rarely. This is one of the few spices where the ground form is the sensible default — amchoor is used as a powder in nearly every dish that calls for it, and grinding hard dried slices is more trouble than it is worth for half a teaspoon. Buy a small jar, keep it genuinely dry, and expect to replace it within a year; the acidity lasts but the fruit character does not, and a caked jar is the usual end. If you cook with it two or three times a year, slices from a South Asian grocer are the better purchase.
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.
