In Southern California, you can find chimeneas at the local hardware store, swap meet, garden center and even on Craigslist. Just to clear things up, a chimenea is not one of those rolled-up, deep-fried burritos known as a chimichanga, nor is it a South American sauce served with grilled meats (chimichurri).
A chimenea, or chiminea, is a portable clay outdoor fireplace that has its origins as a stove and heater in 16th-17th century Mexico. Today, they are still used as fire features on patios, although some people think they look like giant Mexican vases with hand-painted flowers or other motifs, and use them as decorative elements in their outdoor living rooms.
