Mustard oil is a type of vegetable oil made from mustard seeds. It has a distinct, pungent aroma and a slightly spicy, sharp flavor. The oil is commonly used in cooking, particularly in Indian, Bangladeshi, and other South Asian cuisines. It’s known for its high smoke point, making it suitable for frying and sautéing.

The oil contains a mix of monounsaturated and polyunsaturated fats, and it also includes omega-3 fatty acids, which contribute to its health benefits, including promoting heart health. Mustard oil is also known for its high content of erucic acid, which has raised some concerns about its long-term health effects, particularly in larger quantities. However, it remains a staple for culinary and medicinal purposes in many parts of the world.
