I see I'm about to go against the trend again, but, I like her. She's done a lot of good work over the years and a lot of people have been able to gain the basics of cooking as a result of her work. As for her as a person.. I don't know her and I'm not going to judge based on the false environment of TV series. I certainly wouldn't touch her how to cheat thing though, I have Nigella's version and it's much higher quality (and I don't need to listen to her ridiculously false way of speaking to read it thankfully).
I did buy Delia's How to Cook (the combined version that was released recently) a few months ago and am finding it very helpful to fill in basic knowledge on many points I'd missed by being self-taught rather than having someone show me. I'm now actively recommending it to various student friends or older people who want to make the switch from microwave meals to cooking for themselves.
