Heston Blumenthal seems to have cornered the market in envelope-pushing cookery (snail porridge, bacon and egg ice cream, dry ice with everything) but he's not the only one. Somehow, Paul A Young's favoured medium, chocolate, lends itself more readily to playing crazy games; the Puritan in me rebels against doing anything strange with meat and two veg, but pudding is the fun bit, so it's OK to take a few chances. I wouldn't risk my eyebrows with a Heston recipe, but I'd have a crack at some of Young's ideas. And yes, Marmite and chocolate really does work!
