Sarson, also known as mustard oil, is a type of vegetable oil extracted from the seeds of the Brassica juncea plant. It is commonly used in Indian and Southeast Asian cuisine. Mustard oil is rich in monounsaturated and polyunsaturated fats, and is high in erucic acid, which can provide health benefits when consumed in moderation. Browning, on the other hand, refers to the process of caramelization or browning of food, which can enhance its flavor and appearance. When used together, sarson browning can refer to the practice of browning mustard oil before using it in cooking
