Chilli powder, a powdered spice mix comprise of chilli peppers, either red peppers or cayenne peppers, has become the basic ingredient in majority of cuisine. It can be a mix of either pure powdered chillis, or it may contain other additives, like cumin, oregano, garlic powder and salt. Other spices like black pepper, cinnamon, cloves, coriander, mace, nutmeg, etc. are also used in preparing chilli powder. As a result of different ingredients, the spiciness of any given chilli powder is incredibly variable. As a rule, the purer the chilli powder is, the more spicy it is. Many people prefer home made chilli powder, but many versions are also available commercially.
