Turmeric – (Curcuma longa, also called tumeric or kunyit in some Asian countries) is a spice commonly used in curries and other South Asian cuisine. Its active ingredient is curcumin. It is a significant ingredient in most commercial curry powders. Turmeric is also used to give a yellow color to some prepared mustards, canned chicken broth, and other foods (often as a much cheaper replacement for saffron). It makes a poor fabric dye as it is not very lightfast (the degree to which a dye resists fading due to light exposure).
