Mustard oil is a pungent and flavorful oil derived from the seeds of the mustard plant. It is commonly used in cooking, especially in Indian and Bangladeshi cuisines, for its distinctive taste and aroma. Mustard oil is rich in monounsaturated and polyunsaturated fats, as well as vitamins and minerals, making it a popular choice for both culinary and medicinal purposes. Additionally, it has a high smoke point, making it suitable for various cooking methods such as frying and sauting. However, it should be used in moderation due to its strong flavor and potential health risks associated with excessive consumption.
