Ground turmeric is a vibrantly colored spice derived from the root of the Curcuma longa plant. It has an intense golden hue, accompanied by a warm, slightly bitter, peppery flavor and a mustardy aroma. The fine, orange-yellow powder is a key ingredient in an array of dishes, often used in Indian, Middle Eastern, and Southeast Asian cuisines. It's famously used as a main component in curry powders, giving them their iconic color. Besides its culinary uses, ground turmeric is infamous for its purported health benefits, thanks to the key active ingredient called curcumin. It is recommended to store it in a cool, dry place away from sunlight to maintain its potency and freshness.

Ground turmeric is usually found in the spices and herbs section of a grocery store.
