Turmeric known as Circuma longa, once processed from the rhizomes, is a deep organist yellow powder. It is used mainly to color foods. When it comes to flavor, the spice tastes slightly bitter and peppery with undertones of earthy flavor. Though used mainly as a powder, turmeric is also used fresh in its rhizome form in certain regions of the world. Turmeric is grown in Southeast Asian countries due to their tropical climes but is native to southwest India.
