For some reason, TV is becoming obsessed with air fryers. On Wednesday Channel 5 broadcast Air Fryers: Do You Know What You’re Missing? – two weeks after Air Fryers vs Microwaves: Which is Better?, and let’s not forget the Christmas special: Air Fryers: Christmas Made Easy. Channel 4 has also got in on the act, with Air Fryers: Are They Worth It? But why? There can’t be that much content about air fryers, right? Do these shows actually tell us anything about air fryers that we don’t already know? There’s only one way to find out – I watched them all.
