DENISE VAN OUTEN EXPLORES AIR FRYERS FOR CHANNEL 4

Denise van Outen lifts the lid on Britain's air fryer obsession and asks the questions on everyone's lips: how do they work?

What can and can't we cook in them? Can they really save us time and money? And can they bring us more health benefits than other ways of cooking?

Along with an army of home testers, Denise reveals the secrets behind the biggest kitchen revolution since the microwave, as she meets air frying fanatics, explores the science and technology, tries out recipes and conducts taste tests to ask: should we all have one and are they really worth it?

Air Fryers: Are They Worth It airs Friday 23rd June on Channel 4.
