If you know how to cook with a fan oven, you know how to cook with an airfryer which is essentially a small/mini fan oven. "Airfryer" is a bit of a misnomer. We're finding ours fantastic, the food is great and the amount of energy used is far less than heating up a large conventional oven.
Yeah, this is the thing, and is why Rayner is way off the mark. The current trend for them has precisely fuck all to do with them mimicking frying, and everything to do with people being shit scared of energy prices... Potential health benefits too, but I think the energy side is what's really kicked off this recent boom. I bought one of the Cosori's recently and ended up recommending it to a friend's parents (with a shitload of caveats); first thing they cooked in it was a lemon drizzle cake. Because it's a small oven.
Rayner also apparently can't cook. Which is, I suppose, more surprising than it should be. Ok, maybe he just precisely followed recipes (the Cosori ones are sometimes laughably bad), but that's just daft. And you can see in the chicken recipe he's put too much in.
And y'know, oven chips are bad. Fine. That's life... But what are you going to do on a night in? Heat up a large pan of oil on your hob and go through the enormous faff of prepping and cooking deep fried chips (even ignoring health stuff)? If you want an acceptable sauce vehicle to go with a few light ales, it's fine. Just a different thing. Though to refute myself a bit you can do a kind of semi-deep fry for most fried stuff, which isn't so bad. Does still use a fair bit of oil, and is obviously less healthy. Or more energy dense perhaps, healthy being relative.
He ends up reviewing hype that isn't really relevant to the current trend, and mentioning the reason I think most people are buying in passing at the end. Engaging with that, and basing his review on it would have been... more helpful.
