Chili powder (also powdered chili, chile powder or chilli powder) is the dried, pulverized fruit of one or more varieties of chili pepper, sometimes with the addition of other spices (also sometimes known as chili powder blend). It is used as a spice to add pungency or piquancy and flavor to dishes. In American English, the name is usually spelled "chili". In British English the spelling "chilli" (with two "l"s) is used consistently.
Chili powder is used in many different cuisines, including American cuisine, particularly in Tex-Mex, Chinese, Indian, Korean, Mexican, Portuguese, and Thai. Chili powder blends are the primary flavor ingredient in chili con carne.
