TURMERIC / HALDI GOTA

Turmeric (Curcuma longa) is a rhizomatous herbaceous perennial plant of the ginger family, Zingiberaceae. It is native to tropical South Asia and needs temperatures between 20°C and 30°C (68°F and 86°F) and a considerable amount of annual rainfall to thrive.[3] Plants are gathered annually for their rhizomes, and propagated from some of those rhizomes in the following season.

When not used fresh, the rhizomes are boiled[citation needed] for several hours and then dried in hot ovens, after which they are ground into a deep orange-yellow powder commonly used as a spice in curries and other South Asian and Middle Eastern cuisine, for dyeing, and to impart color to mustard condiments. Its active ingredient is curcumin and it has a distinctly earthy, slightly bitter, slightly hot peppery flavor and a mustardy smell.

Production and etymology

India and Pakistan are significant producers of turmeric which has regional names based on language and country. The name appears to derive from the Latin, terra merita (merited earth) or turmeryte, possibly related to saffron. As turmeric is a natural botanical compound, it is not patentable.

History

Turmeric has been used in India for thousands of years and is a major part of Ayurvedic medicine. It was first used as a dye and then later for its possible medicinal properties.

Uses

Turmeric grows wild in the forests of South and Southeast Asia. It is one of the key ingredients in many Asian dishes. Indian traditional medicine, called Ayurveda, has recommended turmeric in food for its potential medicinal value, which is a topic of active research. Its use as a coloring agent is not of primary value in South Asian cuisine.

Turmeric is mostly used in savory dishes, but is used in some sweet dishes, such as the cake Sfouf. In India, turmeric plant leaf is used to prepare special sweet dishes, patoleo, by layering rice flour and coconut-jaggery mixture on the leaf, and then closing and steaming it in a special copper steamer (goa).

In recipes outside South Asia, turmeric is sometimes used as an agent to impart a rich, custard-like yellow color. It is used in canned beverages and baked products, dairy products, ice cream, yogurt, yellow cakes, orange juice, biscuits, popcorn color, sweets, cake icings, cereals, sauces, gelatins, etc. It is a significant ingredient in most commercial curry powders.

Most turmeric that is used is in the form of rhizome powder, in some regions (especially in Maharashtra, Goa, Konkan and Kanara), turmeric leaves are used to wrap and cook food. This use of turmeric leaves usually takes place in areas where turmeric is grown locally, since the leaves used are freshly picked. Turmeric leaves impart a distinctive flavor.

Although typically used in its dried, powdered form, turmeric is also used fresh, like ginger. It has numerous uses in Far Eastern recipes, such as pickle made from fresh turmeric that contains large chunks of soft turmeric.
