In cooking, sometimes the simple things are best. When at home, Henri Soulé, the celebrated owner of New York’s Pavillon and Côte Basque restaurants, loves to serve brandade de morue, a delicious purée of salt cod. Mario Gallati, the guiding light behind three famous London restaurants, the Caprice, the Empress and the Écu de France, like nothing better than a huge plate of chicken wing-tips. René Hure, proprietor of the Hostellerie de la Poste in Avallon, one of France’s greatest restaurants, prefers to serve an earthy pot-au-feu of beef, pork and chicken, simmered in beef stock, when he entertains special guests.
