Tamarind is the brown pod pulp of Tamarindus indica, a long-lived leguminous tree of the Fabaceae family, and one of the few sour agents on the planet whose acidity comes not from citric but from tartaric acid, the same acid as grape. The pod is a curved brown shell, 8 to 15 centimetres long, containing three to ten glossy black seeds embedded in a sticky fibrous paste that runs 12 to 18 percent tartaric acid, 20 to 40 percent sugars and 2 to 3 percent pectin; that sugar-to-acid ratio is the reason tamarind reads not as sharp like lemon but as deep, raisin-like and almost worcestershire. India is both the largest producer and the largest consumer, with Andhra Pradesh, Karnataka and Tamil Nadu accounting for the bulk of the crop; Thailand specialises in the sweet dessert variety from Phetchabun province, eaten fresh like a date; Mexico, concentrated in Colima, Jalisco and Guerrero, supplies the domestic agua de tamarindo and candy market and the Mexican diaspora in the United States. The Caribbean, Sudan, Senegal and the Philippines fill the rest. The spice enters South Indian sambar, rasam and puli kuzhambu, Thai pad thai, tom yum and massaman, Indonesian sayur asem, Mexican agua fresca and pulparindo candy, Jamaican chutney, Sudanese aradeib, Filipino sinigang, and, notoriously, the British HP and Worcestershire sauces.
Tasting notes
tangy · dried-fruit · fermented-sweetness
Deep raisin and date entry on the palate, a pronounced tartaric spike clearer and rounder than lemon, secondary notes of worcestershire-molasses, wet brown sugar and roasted carob, and a long sour-sweet tail that hangs on like dried apricot; the concentrate paints a dish dark and tangy without the brightness of vinegar.
Flavor compass
Indian subcontinent, Thailand (Phetchabun), Mexico (Colima, Jalisco, Guerrero), India.
The Petchabun sweet tamarind cultivar, eaten fresh as a dessert fruit. Elongated pods with thick honey-caramel flesh, acidity below 3 %, sugars above 60 %. Graded AAA for export and commanding premium prices in China and Japan.
The classical culinary cultivar from Tamil Nadu, Andhra Pradesh and Karnataka. Sticky deseeded paste or dried pods, 12-18 % tartaric acid, the backbone of sambar, rasam, pulihora and Hyderabadi biryani.
The naturalised Mexican form brought by the Manila galleon trade in the 17th century, now grown in Colima, Jalisco and Guerrero. Shorter pods, medium acidity, used in agua de tamarindo, pulpa candies and Yucatecan mole negro.
Pale yellow flowers with red veining bloom in the dry heat, pollinated by honey bees — the tree needs no water during flowering.
Long brown pods form and slowly ripen on the tree, pulp darkening from green to mahogany as sugars and acids concentrate.
Ripe pods are knocked down with long poles — the shell is brittle and cracks to reveal sticky dark pulp around hard seeds.
Workers press pulp off the seeds by hand; sweet varieties (Thai) eaten fresh, sour (Indian) pressed into cakes.
Indian sour pulp pressed into compact blocks with seeds removed, or soaked and strained into smooth paste.
Blocks keep 2+ years; liquid concentrates 12–18 months refrigerated. Always taste — acidity varies hugely between batches.
The molecules that make it taste like Kampot — and not like anything else.
HPLC of Tamarindus indica pulp: unique among edible legumes, tamarind carries 8–18% tartaric acid — the same organic acid that defines wine grapes. Sugar levels of 30–40% balance it, producing the characteristic sweet-sour-fruity profile.

“Tamil Nadu's apex cooperative federation for tamarind, gathering 14 600 farmers across the Deccan plateau and dominating India's deseeded block and concentrate exports.”
MethodsIndigenous Tamarindus indica trees 30-80 years old in rainfed agroforestry parcels, pods hand-picked March-April, sun-dried on the tree then deseeded mechanically, pressed into 500 g blocks with sea-salt preservation. Concentrate is evaporator-reduced without added acid. All shipments pass FSSAI and NABL lab tests for aflatoxin B1 and heavy metals.

Plant
Tamarindus indica is in the Fabaceae (pea and bean) family, but its pod's fleshy pulp is unusual — carrying 8–18% tartaric acid and 30–40% sugar, a profile closer to wine grapes than to beans. The seeds inside are actually used like beans in parts of India during famine years.
