Tandoor
Also: tandoor oven, tandoori, tandur, tandir, tandır, tonir
A cylindrical clay or masonry oven fired from within by wood or charcoal, reaching 400–480 °C, used across South and Central Asia for baking flatbreads, roasting marinated meats, and cooking tandoori dishes.
/tan-DOOR/From Hindi/Urdu तंदूर / تندور (tandūr), from Persian تنور (tanūr), from Akkadian tinūru — a clay cooking vessel; cognates appear across the Caucasus (tonir in Armenian), Central Asia (tandir in Uzbek/Azerbaijani), and Turkey (tandır); the oven form is attested in the Indus Valley Civilization ca. 2600 BCE
Definition
The tandoor is a cylindrical oven, typically 60–120 cm tall and 40–80 cm in diameter at the widest point, tapering toward a smaller opening at the top. It is made from clay — sometimes mixed with yogurt, sand, or horsehair for crack resistance — and is fired by a bed of wood or charcoal burning at the base. The internal temperature of a fully fired tandoor reaches 400–480 °C (750–900 °F), with the clay walls radiating intense dry heat from all directions and the fire at the floor contributing convective hot air that rises through the chamber and exits from the open top. This combination of radiant heat from the walls and convective heat from below is what makes the tandoor culinarily unique: flatbreads (naan, roti) are slapped against the interior wall and cook in 60–90 seconds by the contact heat of the clay; kebabs and marinated meats threaded on long skewers descend through the top opening and roast in the rising heat without touching a surface. The high temperature causes the bread's surface water to flash-steam, creating the blistered, chewy interior and slightly charred exterior that no conventional oven reproduces. Marinated proteins — chicken in yogurt-and-spice (tandoori marinade), lamb seekh kebab, paneer — benefit from the same flash-roast effect: the exterior chars and crisps while the interior stays juicy, a function of the speed and the radiative intensity. Traditional tandoors are buried in the ground or built into a platform, requiring the cook to reach into the oven with a long cushion-tipped gaddi (pillow) for bread or hooked skewer rods for meat. Modern restaurant tandoors are above-ground and insulated on the outside. Gas-fired versions exist but are generally considered inferior for bread — the combustion chemistry and the ash and smoke from wood or charcoal contribute faint flavor compounds that gas cannot replicate.
In use
“The naan hit the tandoor wall with a practiced slap, adhering instantly as the water in the dough hissed and swelled, blistering in under two minutes into the charred, pillowy bread that came to the table steaming.”

Notes
The three heat sources in one oven
A fired tandoor operates with three simultaneous heat transfer modes: conduction (bread stuck to the clay wall receives direct contact heat); radiation (the glowing walls emit intense infrared heat that chars the exposed face of bread and meats); and convection (rising hot air from the coal or wood base circulates through the chamber). No other common cooking vessel combines all three at such high temperature, which is why tandoor results are structurally impossible to replicate in a standard oven even at its maximum setting.
The tandoori marinade
Classic tandoori chicken (murgh tandoori) is marinated in yogurt, lemon juice, ginger-garlic paste, and a spice blend that typically includes Kashmiri red chili (for color more than heat), cumin, coriander, garam masala, and turmeric. The yogurt marinade serves a dual purpose: it tenderizes the protein via acid and enzymes, and its fat content helps the spices adhere and char without burning cleanly off in the extreme heat. The Kashmiri chili's characteristic brick-orange color on finished tandoori dishes is a marker of quality marinade, not artificial dye.
Regional variants across the diaspora
The tandoor's close relatives include the Armenian tonir (buried in the earth, used for lavash), the Azerbaijani tandir (similar clay pit oven), the Turkish tandır (used for slow-cooked lamb), and the Central Asian tandir (bread-centric, in Uzbekistan and Tajikistan). All descend from the same Mesopotamian clay oven tradition; the divergences are in fuel type, depth, size, and primary product (bread versus meat).
