Three different types of oil are made from mustard seed and may be referred to as “mustard oil.” The first is a fatty vegetable oil that comes from pressing the seeds. The second is called essential oil and is made by grinding the seeds, mixing them with water and extracting the oil through distillation. The third involves infusing mustard seed extract with other vegetable oils. All three types of mustard oil are known for their pungent, nutty taste and somewhat controversial health benefits.
Although extremely popular in northern India, Nepal, Bangladesh, and Korea, mustard oil was once considered unsafe to eat in the United States, Canada and much of Europe because it contains erucic acid. In fact, mustard oil sold in the U.S. must be labeled “not for human consumption” and has only been approved for use as a massage oil.
Initial studies of the effects of erucic acid on rats showed the substance to be harmful, however it is now generally believed that those studies were flawed and that the rats reacted poorly to other oils that are considered safe for humans, too.
You can buy mustard oil in Indian groceries. American chefs have been discovering it of late, as described in this New York Times article, American Chefs Discover Mustard Oil. Look for a high quality cold pressed oil from New Zealand or Australia and never buy mustard oil made through distillation.
