Chili powder—as a blend of spices—is composed chiefly of chile peppers and mixed with other spices including cumin, oregano, garlic powder, and salt. While there is some agreement about which spices this blend should contain, the amount of each is a matter for debate. This is not improved by the linguistic confusion between “chili powder”—as a blend of spices—and the “chili powder”—as in powdered dried chilies—used in those blends. In addition to the basic ingredients, some add other herbs and spices and still call it “chili powder.”
