Chilli Powder
Chilli powder 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). It is used as a spice (or spice blend) to add pungency (piquancy) and flavour to culinary dishes.
Varients
Chili powder blends are composed chiefly of chili peppers and blended with other spices including cumin, onion, garlic powder, and sometimes salt. The chilis are most commonly red chili peppers; "hot" varieties usually also include cayenne pepper. As a result of the varying recipes used, the spiciness of any given chili powder is variable.
