What is cooking oil smoke point?

The temperature at which an oil starts to smoke is called the Smoke Point of the oil. It is important to know the smoke point of the oil in which you cook as no one wants to burn their oil. If an oil is over heated, it releases potentially toxic compounds.

Smoke points should be considered as a generalised value rather than a precise value. The surface area of the pan also plays an important role, for example a deep pan with a thin layer of oil will have a different smoke point than a wide shallow pan.
