Instead of using fat to make chips, this revolutionary kitchen appliance uses super heated air.But now HOT has invented a frying machine that gives you that same satisfying fatty taste - but without the oil.The Air Fryer uses Rapid Air Technology, hot air in other words, to cook the kind of meals that would traditionally be dunked in a deep fat fryer.By circulating air up to 200 C around foods like chips, chicken, fish or pastries, HOT claims to be able to brown them off nicely with up to 80 percent less fat.
