DESC: Go ahead! Fry your potatoes after frying the fish. (That is if you want to.) You won’t get any lingering fishy taste. Here’s why: This professional deep fryer is so much more advanced than non-professional fryers because of its specially developed odor filtered Cool Zone technology. It stops “taste-transfer” from burning food particles, keeps oil cleaner, hotter, cooks food faster with little to no oil absorption.
