Fascinating story about Hervé This, cooking scientist –
He can measure the pressure inside a chip and has worked out how to produce 24 litres of mayonnaise from a single egg…
His specialism is the science of cooking. For him, every foodstuff is ‘a chemical mixture’. ‘When aromatic compounds are formed on the surface of a roast,they are the result of a chemical reaction. When mushrooms turn black after being chopped, it is the fruit of a chemical reaction.’
Over the years, his musings on chemical reactions have led to a number of discoveries. He has worked out how to uncook an egg. He has calculated that you can produce 24 litres of mayonnaise with a single yolk. He has invented a Béarnaise sauce by replacing butter with melted chocolate, as well as ‘chocolate chantilly’ (a form of whipped chocolate prepared in the same way as crème chantilly). He’s baked an egg for an hour at 55°C, managing somehow to leave the yolk ‘exceptionally smooth and tender’.
