Toast the cumin seeds in a dry skillet over medium heat until you just begin to smell them. Grind the cumin seeds with a small coffee grinder or mortar and pestle. You can use store-bought ground cumin instead for an easier option, but toasting the cumin seeds really brings out the flavor.
Put all the ingredients in a small bowl, and mix thoroughly.
Store in spice jars in the refrigerator or in the pantry until ready to use.
