What is a tandoor?

These kinds of ovens are used throughout the Middle East, India, Pakistan, and even parts of Central Asia and China. They can be large, permanent structures ensconced in a kitchen or outdoor area, or they can be smaller, portable ovens that can be carried from place to place. The word "tandoor" is said to have been derived from Persian word ‘Tannur’, derived from the Babylonian word ‘tinuru’ based on Semitic word ‘nar’ meaning fire.

Regardless of size, shape, or region of origin, all tandoor ovens operate on essentially the same principle. The ovens are made of clay with some sort of insulating material like concrete or mud on the outside. They are cylindrical and often curve inward toward the top like a beehive or jug to concentrate the heat. A top opening is left clear to allow access and ventilation.

One of the biggest advantages of these ovens is that once they are heated, they will maintain a consistent high temperature for hours with very little additional fuel. This is a big plus in parts of the world where fuel is scarce.
