Chili is widely used, although in much of South America the plant and its fruit are better known as ajÃ, locoto, chile, or rocoto. However, this spelling is discouraged by some in the United States of America, since it also commonly refers to a popular Southwestern-American dish (also known as chili con carne (literally chili with meat); the official state dish of Texas), as well as to the mixture of cumin and other spices (chili powder) used to flavor it. Chili, as in the case of Cincinnati chili, can also refer to ground beef stews that do not actually contain any chile peppers. Chili powder and chile powder, on the other hand, can both refer to dried, ground chili peppers. Chili pepper (also known as, or spelled, chilli pepper, chilli, chillie, chili, and chile) is the fruit of the plants from the genus Capsicum, members of the nightshade family, Solanaceae. Botanically speaking, the fruit of capsicums are berries. Depending on flavor intensity and fleshiness, their culinary use varies from use as a vegetable (eg. bell pepper) to use as a spice (eg. cayenne pepper). It is the fruit that is harvested. Chili peppers originated in the Americas; and their cultivars are now grown around the world, because they are widely used as food and as medicine. An oil is a substance that is in a viscous liquid state ("oily") at ambient temperatures or slightly warmer, and is both hydrophobic (immiscible with water) and lipophilic (miscible with other oils, literally). This general definition includes compound classes with otherwise unrelated chemical structures, properties, and uses, including vegetable oils, petrochemical oils, and volatile essential oils. Oil is a nonpolar substance.
