A cylindrical clay oven used, in Middle Eastern and South Asian cuisine, to make flat bread, or to cook meat
You can cook naan in a normal oven, but the results will inevitably disappoint; even Indians generally wait to savour them in restaurants, as very few homes are equipped with a tandoor.
[ tän-'dur ] (noun.) 1840. From Hindustani तन्दूर (tandūr) / تندور (tandūr), from Persian تنور (tannur), from Arabic تَنُّور (tannūr), ultimately from Akkadian tinūru, all meaning oven.
