Chili powder (also spelled chile, chilli, or, alternatively, powdered chili) is the dried, pulverized fruit of one or more varieties of chili pepper, sometimes with the addition of other spices (in which case it is also sometimes known as chili powder blend or chili seasoning mix).[1] It is used as a spice (or spice blend) to add pungency (piquancy) and flavor to culinary dishes. In American English, the spelling is usually "chili"; in British English, "chilli" (with two "l"s) is used consistently.

Chili powder is used in many different cuisines, including American (particularly Tex-Mex), Chinese, Indian, Bangladeshi, Korean, Mexican, Portuguese, and Thai. A chili powder blend is the primary flavor in American chili con carne.[1]

Chili powder is sometimes known by the specific type of chili pepper used. Varieties of chili peppers used to make chili powder include Aleppo, ancho, cayenne, chipotle, chile de árbol, jalapeño, New Mexico, pasilla, and piri piri chili peppers. Gochugaru is a variety used in Korean cuisine traditionally made from sun-dried Korean red chili peppers known as taeyang-cho, with spicier varieties using Cheongyang peppers.[2] Kashmiri chili powder is bright red, but mild in heat and used in Indian cuisine, named after the region of Kashmir.
