It was hard not to be struck by this image: probably pretty unfair, but it rings a certain bell. It is unfair because Nigella might well look just as scrummy if she were a vegetarian, or a vegan. Although, I have to say that when I go into a health food shop (which is not that often) I am struck by how unwell everyone looks.
My brother sent me a link to a mash-up. Not very respectful, but then again, whoever did this must have watched hours of footage to get the relevant bits, which suggests a certain affection.
