The term tandoor refers to a variety of ovens, the most commonly known is a cylindrical clay or metal oven used in cooking and baking. The tandoor is used for cooking in Southern, Central and Western Asia, as well as in the Caucasus.
The heat for a tandoor was traditionally generated by a charcoal or wood fire, burning within the tandoor itself, thus exposing the food to live-fire, radiant heat cooking, and hot-air, convection cooking, and smoking by the fat and food juices that drip on to the charcoal.
Temperatures in a tandoor can approach 480 °C (900 °F), and it is common for tandoor ovens to remain lit for long periods to maintain the high cooking temperature. The tandoor design is something of a transitional form between a makeshift earth oven and the horizontal-plan masonry oven.
