Extra virgin Olive oil for many things, yet anything that needs deep fry high temperatures I use coconut shortening. Like French fries I use coconut shortening.
There's is a difference in temperatures between shortening and oil. For frying shortening doesn't burn as quickly..
So coconut shortening at 450°f is perfect for french fries. Corn oil smoke point is at 440°f and vegetable oil is at 400°f.
Peanut oil just doesn't taste right to me for frying.
