Turmeric (yellow ginger)

casaveneracion.com Turmeric (yellow ginger)

One of the five spices that make up yellow curry paste or powder, turmeric (also called yellow ginger and curcumin) is often used to add a deep yellow color to dishes. It is more than a coloring agent though since it imparts a distinct peppery flavor of its own. Unpeeled, it looks like a small ginger. Peeled, the flesh is a deep yellow (almost orange) in color. Fresh turmeric is prepared in much the same way as ginger. It is peeled then ground (traditionally, with a mortar and pestle) before it is added to food.
