Chili power (also spelled chile powder) is a generic name for any powdered spice mix composed chiefly of chili peppers, most commonly either red peppers or cayenne peppers, which are both of the species Capsicum annuum. But it can be made from virtually any hot pepper including ancho, Cayenne, Chipotle, New Mexico, and pasilla chilis. The spice mix may simply be pure powdered chilis, or it may have other additives, especially cumin, oregano, garlic powder, and salt. Some mixes may even include black pepper, cinnamon, cloves, coriander, mace, nutmeg, or turmeric. As a result of the various different potential additives, the spiciness of any given chili powder is incredibly variable. As a rule, the purer the chili powder is, the more spicy it is.
