I bought an el cheapo Phillips air-fryer a couple of years ago to cook Jeff chips (I dislike the smell of hot fat frying anything). Not only does the little beast do fabulous chips in a handful of minutes, but I was amazed at the other things you can do it it. I've cooked pies, an entire chicken and a deep dish rice pudding in it before.
