Southwestern flavour is a culinary style that originated in the American Southwest, particularly in states like Arizona, New Mexico, and Texas. It is characterized by the use of bold and spicy ingredients such as chili peppers, cumin, garlic, and oregano, as well as the incorporation of indigenous ingredients like mesquite, beans, corn, and tomatoes. Southwestern cuisine blends traditional Mexican, Native American, and Anglo-American cooking techniques to produce dishes like tacos, enchiladas, chili, and tamales, which are often served with sides like guacamole, salsa, and rice.
