I chose warm smoked eel with roast beetroot and horseradish cream, a classic that used the plumpest, meatiest Dutch eel. Friend Antonia went for sautéed calves' brains with brown butter and capers. She liked the delicate moussey texture and flavour but the next day she e-mailed me: 'Cracking meal, but in postscript I must say that as a cranial virgin I felt traumatised about scoffing brains.' She's right, there is something challenging about consuming brains. I don't like eating them, and neither does my father, a surgeon, having decided on health grounds that nervous tissue (optic nerve, spinal chord, brain) could carry some pretty hairy diseases in any beastie.
