Oil must be super hot for frying
You don't have to risk setting your kitchen ablaze the next time you make French fries by starting with a sizzling pan of hot oil. You can start your fries in room-temperature oil and slowly heat things up. Frying may take longer this way (up to an hour), but you'll use less oil with no spattering and you won't have to stand guard over the pan the whole time. The resulting fries will be crispy and brown, but with about one-third less fat because less oil will be absorbed as they cook.
