Red Pepper is made from the ground fruit of a plant in the Capsicum family. The fruits, commonly known as "chilies" or "chili peppers," are fiery red or orange pods which rarely grow to more than 4 inches in length. The ground product ranges from orangered, to deep, dark red. According to the American Spice Trade Association, "Red Pepper" is the preferred name for all hot red pepper spices. Cayenne Pepper is another name for the same type of product. Some manufacturers use the term Cayenne Pepper to refer to a hotter version of Red Pepper. Capsicum peppers are native to Mexico, Central America, the West Indies, and parts of South America. The Spanish discovered the pods in the New World and brought them back to Europe. Before the arrival of Spaniards, Indians in Peru and Guatemala used capsicum medicinally to treat stomach and other ailments A powder is a dry, bulk solid composed of a large number of very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials, although the terms powder and granular are sometimes used to distinguish separate classes of material. In particular, powders refer to those granular materials that have the finer grain sizes, and that therefore have a greater tendency to form clumps when flowing. Granulars refers to the coarser granular materials that do not tend to form clumps except when wet.
