I *think* I understand who her market is. There is so much hype about cooking and food sourcing etc these days. Just turn on the TV. Last night I watched Recipe for Success, The Great British Menu, Delia, and then Breaking into Tesco. (I hope I got all those names right)
Anyway, yes, there are plenty of people out there who no matter what you say or do can't or won't cook. Fair enough. But I think she's aiming at people who don't cook because life and circumstances have just got in the way. They've got lazy, or into a habit or whatever. They *know* they should do better and can probably find a bit of time to do so but just need a bit of a kick in the pants. That's the only crowd I can see this appealing to as they are the ones who would actually bother to watch it. Someone who has absolutely no interest in cooking won't even turn this show on.
That said, I still think the show is ill-conceived. She doesn't really show you how to make even the cheaty recipes. The Guardian blogged about it yesterday and I pretty much agree with what they said.
