Chilli powder (also powdered chilli or chile powder) is the dried, pulverised fruit of one or more varieties of chilli pepper, sometimes with the addition of other spices (when it may be known as chilli powder blend). It is used as a spice to add piquancy and flavour to dishes. In American English the name is usually spelled “chili”, or, less commonly, “chile”. In Australia the spelling “chilli” (with two “l”s) is used consistently.
Chilli powder is sometimes known by the specific type of chilli pepper used (such as cayenne pepper). It is used in many different cuisines, including Tex-Mex, Indian, Chinese, and Thai.
Chilli powder blend is composed chiefly of chilli peppers and blended with other spices including cumin, oregano, garlic powder, and salt. The chillies are most commonly either red chilli peppers or cayenne peppers, which are both of the species Capsicum annuum; many types of hot pepper may be used, including ancho, Jalapeño, New Mexico, and pasilla chillies. As a result of the various potential additives, the spiciness of any given chilli powder is variable
