Well I know the standard viewpoint is that although unfashionable, Delia gives sound sensible recipes that produce excellent results, I find when I've tried that most of her recipes produce quite the opposite: dull food, badly cooked (e.g. overcooked, wrong consistency...). So I've given up trying her ideas. Having said that what she says for poached eggs at least sounds plausible.

Jamie Oliver I find quite the opposite. Absurdly affected laddish attitude which makes quite painful reading, and I would never have tried out his recipes if it weren't for a very sensible friend who recommended them to me. And now I own several of his books and find the actual results very pleasing.
(I don't watch cookery programmes - I cook and I eat instead - so I've never seen him on television, so I really meant it when I said painful reading. Same goes for many "celebrity chefs": I have eaten food they have cooked, and cooked some of their recipes but never once seen them on television.)
