You want to look for one that has a high smoke point. The higher the smoke point, the hotter the oil can get before it starts to burn. Sunflower and peanut oil have the same smoke point of 450. Lard only has a smoke point of 370. However...lard is saturated fat...unhealthy. Peanut is monounsaturated while Sunflower is polyunsaturated - both of which are healthy fats. Why not make it taste good and be healthy.
