A tandoor is a cylindrical clay oven used in Punjab northern India and Pakistan in which food is cooked over a hot charcoal fire. Temperatures in a tandoor can approach 480°C (900°F). It is common for tandoor ovens to remain lit for long periods of time to maintain the high cooking temperature. The word tandoor comes from the Urdu words tandūr and tannūr; these derive from the Persian tanūr, which comes from the Arabic word tannūr, from which Turkish word Tandır (which has the same meaning as explained in the article) originates. It is used for cooking certain types of Indian and Pakistani food , such as tandoori chicken and bread varieties like tandoori roti and naan. (The word tandoori is the adjective form.) Some modern day tandoors use electricity or gas instead of charcoal. It is also known as a tonir in Armenian which is a widely used method of cooking barbeque and lavash bread. On July 2, 1995, the Indian politician Sushil Sharma was accused of murdering his wife, chopping up her body and burning the remains in a restaurant's tandoor oven. This grisly episode came to be known as the Tandoor Murder case. A court found the accused guilty on November 7, 2003, and he was sentenced to death.
