The Fat Duck in Bray has admitted that it accidentally served its owner Heston Blumenthal to customers after a kitchen experiment went wrong. Blumenthal, famed for his scientific approach to cooking, was dished up as aerated foam to unsuspecting diners after he slipped and fell into a vacuum jar whilst cooking. The incident did not appear to affect his guests' attitude to the experience, however. One diner, John Keenan, a management consultant from London, said he was not put off eating at the restaurant. "I had mustard ice cream, and cauliflower with chocolate. To be honest I don't care what I eat there as long as it's all scientific and molecular," he said.
