It is a versatile cooking oil with a mild flavor, high smoke point, and a balanced fatty acid profile. Groundnut oil is commonly used in various culinary applications, including frying, sautéing, and as a base for salad dressings. Rich in monounsaturated and polyunsaturated fats, it is considered a healthier option compared to some other cooking oils.
