Turmeric is the rhizome or underground stem of a ginger-like plant. It is usually available ground, as a bright yellow, fine powder. The whole turmeric is a tuberous rhizome, with a rough, segmented skin. The rhizome is yellowish-brown with a dull orange interior that looks bright yellow when powdered. The main rhizome measures 2.5 - 7 cm (1” – 3 “) in length with a diameter of 2.5 cm (1”), with smaller tubers branching off.
