Just watched Heston Blumenthal’s Chocolate Factory Feast on Channel 4 – as ever, absolutely amazing, though completely mad!  Lickable wallpaper, chocolate waterfall that separates as it flows, and my favourite, duck a l’orange turned in to confectionary (including a chocolate orange made predominantly of duck!)  I can imagine the layered mushroom dish would taste brilliant – I’ve experienced the dry ice / smoking moss first-hand at the Fat Duck – he has a real penchant for the theatrics of food!  I don’t think I’ll be trying any recipes though…
