Turmeric powder is a bright yellow spice that comes from the root of the turmeric plant. It has been used for thousands of years in Asian cooking and traditional medicine. Turmeric has a warm, bitter taste and is commonly used to flavor or color curry powders, mustards, butter, and cheeses. It contains curcumin, a compound that gives turmeric its vibrant color. Curcumin has been studied for its potential health benefits. Research shows it may have anti-inflammatory, antioxidant, and anti-cancer effects. Turmeric powder is available as a ground spice or in capsule form. When cooking with turmeric powder, add it in small amounts as it has a strong flavor. Store in an airtight container in a cool, dark place.
