    Curcuma longa: Dried turmeric rootstock
    Dried turmeric rhizome

    Used plant part

    Rhizome. Fresh turmeric leaves are used in some regions of Indonesia as a flavouring, e.g., in Western Sumatra.

    Plant family

    Zingiberaceae (ginger family).

    Sensory quality

    In fresh state, the rootstock has an aromatic and spicy fragrance, which by drying gives way to a more medicinal aroma. On storing, the smell rather quickly changes to earthy and unpleasant. Similarly, the colour of ground turmeric tends to fade if the spice is stored too long.

    Main constituents

    Turmeric contains an essential oil (max. 5%), which contains a variety of sesquiterpenes, many of which are specific for the species. Most important for the aroma are turmerone (max. 30%), ar-turmerone (25%) and zingiberene (25%). Conjugated Diarylheptanoids (1,7-diaryl-hepta-1,6-diene-3,5-diones, e.g. curcumin) are responsible for the orange colour and probably also for the pungent taste (3 to 4%).

    The Jawanese species C. xanthorrhiza contains 6 to 11% essential oil, which is dominated by 1-cyclo-isoprenemyrcene (up to 85%); it furthermore contains a phenolic sesquiterpene missing from C. longa, xanthorrizol, which makes up max. 20% of the essential oil.

    Origin

    Because of ancient trade, the origin of turmeric cannot accurately be reconstructed; probably South East Asia or South Asia. A related species, C. xanthorrhiza, grows on Jawa, where it is called temu lawak; in taste, it is equivalent to C. longa.

    Etymology

    In many languages, the names of turmeric just mean “yellow root”: Dutch geelwortel, German Gelbwurz, Arabic uqdah safra [عقدة صفرا], Finnish keltajuuri [keltainen “yellow” and juuri “root”] and Modern Greek kitrinoriza [κιτρινόριζα], where kitrinos [κίτρινος] means “yellow”, probably an allusion to lemon or similar citrus fruits. The same meaning is found in the species name of the Jawanese variety of turmeric, C. xanthorrhiza: Ancient Greek xanthe rhiza [ξανθὴ ῥίζα] “yellow root”. Other names relate turmeric to related rhizomes, adding an epithet “yellow”, e.g., Chinese huang jiang [黃薑] and Russian imbir zhyoltyj [имбирь жёлтый] “yellow ginger” (from zhyoltyj [жёлтый] “yellow”) and Czech žlutý zázvor “yellow zedoary”.

    English turmeric derives from the (now obsolete) French terre-mérite (Latin terra merita, “meritorious earth”), probably because ground turmeric resembles mineral pigments (ochre).

    The genus name Curcuma likens turmeric to saffron, the most relevant yellow plant dye in the Ancient World. Curcuma is Latinization of Arabic kurkum [كركم], which originally meant “saffron” but is now used for turmeric only. Compare also the name of saffron in Biblical Hebrew, karkom [כרכם]. In most contemporary European languages, the names of turmeric are derived more or less directly from Latin curcuma. Examples include Finnish, Croatian and Dutch kurkuma, French and Italian curcuma, Spanish cúrcuma, Romanian curcumă and Bulgarian and Russian kurkuma [куркума]. Scandinavian names show stronger variation, e.g., Danish gurkemeje, Norwegian gurkemeie and Swedish gurkmeja.

    The similarity to saffron is reflected by names like “Indian saffron” in several European tongues: German indischer Safran, Croatian indijski šafran, French safran des Indes or Turkish hint safranı. Compare also Spanish azafrán arabe “Arabic saffron”. On the other side, saffron is named nghe tay [nghệ tây] “Western turmeric” in Vietnam, where turmeric is native and saffron just an exotic oddity.

    The toponym India has a long history. It is derived from Sanskrit sindhu [सिंधु] “river”, which was particularly used for the Indus River in North-Western India. There is the speculation that the Sanskrit term itself is a loan from Dravidian languages and corresponds to the Dravidian root CĪNT “date palm tree” (Modern Tamil intu [ஈந்து]). Was the Indus River, then, originally the “river where the palm trees grow”?

    When the Greeks entered the Indus area in the course of their conquest of Central Asia under Alexander the Great, they adapted the term sindhu to form the name of the country: Indike chora [Ἰνδικὴ χώρα] “Indian land” (properly “land around the Indus river”) and later simply India [Ἰνδία]. In the Hellenistic epoch, that name spread westwards to more languages, e.g., Kazakh ündi [үнді], Arabic al-hind [الهند] and Farsi hindustan [هندوستان] “India”; also Farsi hendi [هندی] “Indian”.

    Because of the strong association between India and spices in Europe, many spices contain an “India-Element” in their names. Examples are, besides “Indian saffron” for turmeric, designations like “Indian nut” (coconut, nutmeg), “Indian date” (tamarind), “Indian anise” (star anise), “Indian parsley” (coriander) and many more. In “Indian cress” (nasturtium), however, the epithet points not to India but to Latin America.

    Turmeric is a very important spice in India, which produces nearly the whole world's crop and uses 80% of it. Turmeric usage dates back nearly 4000 years, to the Vedic culture in India, when turmeric was the principal spice and also of religious significance. In today's India, turmeric is still added to nearly every dish, be it meat or vegetables. I found the largest quantities of it in boiled lentils (see also dill) or potatoes. Furthermore, it appears in rice dishes (pullao), although turmeric-dyed rice is not very common in India, which might surprise people who consider curry rice “typical Indian”. Still, turmeric is part of all curry powders (see curry leaves for more information on this Anglo-Indian spice mixture). Due to Indian influence, turmeric has also made its way to the cuisine of Ethiopia (see long pepper).

    In South East Asia, the fresh spice is much preferred to the dried. In Thailand, the fresh rhizome is grated and added to curry dishes; it is also part of the yellow curry paste (see coconut for more on Thai curries and curry pastes).

    Yellow rice (nasi kuning) is popular on the Eastern islands of Indonesia; it derives its colour from fresh or dried turmeric. In Bali, where alone in Indonesia Hinduism has survived, a tasty nasi kuning is prepared from rice, turmeric, coconut milk and aromatic leaves (Indonesian bay-leaf, lemon grass and pandanus leaves). It is considered a “cultic dish” and sacrificed to the Gods; no-one who has ever visited Bali will forget the masses of Balinese streaming to temples and sacrificing, among other gifts, cones of yellow rice, e.g. in Bali's most important temple at Besakih (see also Indonesian bay-leaf for some details about Balinese cooking and lesser galanga for a famous Balinese recipe). On Jawa, Indonesia's most populous island, Hinduism has been abolished in favour of Islâm; yet nasi kuning is still held a somewhat sacred dish. Moreover, Indonesian cooks frequently add dried turmeric to their stews and curries (see greater galangale for an example).

    Western cuisine does not use turmeric directly, but it forms part of several spice mixtures (see above about curry powder) and sauces; it is also used to impart a bright yellow colour to mustard paste (see white mustard seed).

    Turmeric is sometimes confused with saffron because of similar staining capabilities, although saffron gives a more orange colour. Since turmeric does not share the fascinating aroma of saffron, it is not an acceptable substitute or even alternative to it! See annatto for a survey of food colourings.

    The so-called white turmeric is a closely related plant (zedoary), whose fresh rhizome is not so much used as a spice, but eaten as a very tasty vegetable. You can do the same with ordinary yellow turmeric, but it will stain your teeth yellow.

    Turmeric's staining capability may seem a nuisance to everybody who must clean cooking utensils – cutting boards are particularly hard to clean with brush and soap alone. The dye is, however, not light-proof and fades away after but one hour in direct sunlight.
