Mustard oil, which is produced from the seeds of the mustard plant, is a common ingredient in Indian cuisine. Known for its strong flavour, pungent aroma, and high smoke point, it's often used for sautéing and stir-frying vegetables in many parts of the world.
The oil is made by pressing of the seeds or by the process of grinding, whereby it is mixed with water and then further distilled. The black mustard yields a lighter coloured and stronger tasting oil, while the white variety produces a yellowish coloured, pungent oil.
