Black cardamom is a variety of cardamom that is dried over a fire, imparting an intensely smokey flavor. Unlike green cardamom, black cardamom should only be used for savory dishes. You can use the pods whole, grind them, or just grind the seeds. Drop a few pods into rice as it cooks. Add to spice mixes along with cinnamon, clove, and nutmeg for long simmering curries to highlight its flavor.
