Some years ago, I remember watching a 'one-off' 'cheffy' programme and the chef said that, to become good in the food industry, you need to be able to find the exact word to describe foods, so that the listener / watcher can be riding alongside you and be only short of the real taste. I think Nigella Lawson is an interesting chef and probably the only programme I would sit through, from beginning to end. If she chooses words to describe a food's texture or taste, I can feel it, too. As for 'kitchen porn (I've never heard of it before and imagined scantily-clad' wannabees), I think some words likely 'the sexy, smooth, flow of the white chocolate off the back of the spoon (my words)' sounds inviting but not sexual. I'd definitely want to 'go all the way'.
