What Is the Best Oil to Deep Fry Fish?

For the high heat involved in deep frying fish, the best oil is one with a high smoke point, such as peanut oil, canola oil, sunflower oil and safflower oil. The smoke point is the temperature at which a fat starts breaking down and smoking due to the heat. With smoke points well above 400 degrees, these oils generally maintain proper deep-frying temperatures safely without burning.
