This classic French boiled beef dish (which translates as "pot on fire") is simple to prepare and yields a double dividend: the cooking broth is served as a soup for the first course, while the cooked beef and vegetables form the main course. In France, this popular dish arouses considerable passions and every year, pot au feu festivals are held across the country. A good pot au feu cannot be rushed: allow at least 4 hours for the brisket to cook. Serve the soup with good crusty bread, and as optional garnishes, offer cornichons, pickled onions, mustard, and horseradish.
