A tandoor (/tænˈdʊər/ or /tɑːnˈdʊər/) is a large vase-shaped oven, usually made of clay. Since antiquity, tandoors have been used to bake unleavened flatbreads, such as roti and naan, as well as to roast meat. The tandoor is predominantly used in Western Asian, Central Asian, South Asian, and Horn of Africa
The standard heating element of a tandoor is an internal charcoal or wood fire, which cooks food with direct heat and smoke. Tandoors can be fully above ground, or partially buried below ground, often reaching over a meter in height/depth. Temperatures in a tandoor can reach 480 °C (900 °F; 750 K), and they are routinely kept lit for extended periods. Therefore, traditional tandoors are usually found in restaurant kitchens. Modern tandoors are often made of metal. Variations, such as tandoors with gas or electric heating elements, are more common for at-home use.
