urchins – are fashioned into a course that has the appearance of the shore's edge, complete with sea ‘spume’ and edible sand. It is served on a glass-topped box containing real sand, and accompanied by headphones relaying the sounds of seagulls and the sea by means of a small iPod (placed in a conch shell) and earphones. The idea, according to Blumenthal, was one ‘of creating a world, of transporting the diner – through sound, through food, through an integrated appeal to the senses – to another place’. Signature dishes Blumenthal's most famous signature dishes include triple-cooked chips, snail porridge, bacon-and-egg ice cream and parsnip cereal, mock turtle soup (which combines a multi-sensory experience with historical references), Meat Fruit, and his Sweet Shop petit fours. He has pioneered the use of sound as part of the dining experience with his Sound of the Sea dish where diners listen to a recording of the seaside – crashing waves with occasional sounds of distant seagulls, children's laughter and the horn of a ship, while they eat a dish of king fish, konbu cured halibut, ballotine of mackerel with 5 different seaweeds, sea jelly beans and monks beard served on "sand" made from tapioca starch, toasted Japanese breadcrumbs, miso paste and dried seaweeds. Blumenthal is also known for his use of scented dry ice. Blumenthal and his restaurant "The Fat Duck" have been credited as instigators of the bacon dessert "craze". He was preparing sweet and savoury bacon-and-egg ice cream as early as 2004, and news "about the intriguingly odd confection quickly spread through the food world." Historic influences Blumenthal uses British history in his dishes. He became interested in historical cooking in the late 1990s upon obtaining a copy of The Vivendier, a translation of a fifteenth-century cookery manuscript that contained unusual recipes, such as a chicken that appears roasted but wakes up as it is served. He said "I'd had little idea the cooking of the past could be so playful, audacious and creative." Following this, he attended an Oxford Symposium of Food and Cookery where he met the food historians Richard Fitch, who works for Historic Royal Palaces and Marc Meltonville. Later he met a third food historian, Ivan Day and, in consultation with these three, began developing dishes inspired by recipes in historical British cookbooks. The first completed dish based on a historic recipe was Quaking Pudding, which is
