Chili Powder

Chile powder or powdered chili is the ground, dried fruit of one or more varieties of chili pepper, sometimes with the addition of other spices, when it may be known as chili powder or chili powder blend. It is used as a spice to add piquance and flavor to dishes. In American English the name of the fruit or the pure powder may be spelled "chile" or "chili", and in the blend it is spelled "chili". In British English the spelling "chilli" is used consistently.
Chili powder is sometimes known by the specific type of chili pepper used (such as cayenne pepper). It is used in many different cuisines, including Indian, Tex-Mex, Chinese and Thai.

Chili powder blend
Chili powder blend or chili powder is a powdered spice mix composed chiefly of chili peppers and blended with other spices including cumin, oregano, garlic powder, and salt. Mixes may even include black pepper, cinnamon, cloves, coriander, mace, nutmeg, or turmeric. The chilis are most commonly either red peppers or cayenne peppers, which are both of the species Capsicum annuum; many types of hot pepper may be used, including ancho, JalapeƱo, New Mexico, and pasilla chilis. As a result of the various different potential additives, the spiciness of any given chili powder is variable.
Chili powder blends are especially popular in American cuisine, where they are the primary flavor ingredient in chili con carne. The first commercial blends of chili powder in the U.S. were created in the 1890s by D.C. Pendery and William Gebhardt for this dish.
