``Top Chef Masters'' returns for its third season with a new format, new host and new judging panel. The new format is more like the original ``Top Chef'' than in past years. Each week, one of the 12 chefs is eliminated until only one chef remains -- who will win the grand prize of $100,000 for his or her chosen charity. Celebrity chef Curtis Stone takes over as host this season. Author and magazine editor James Oseland returns to the judging panel for the third consecutive year, joined by new judge and food critic Ruth Reichl. Celebrity guest judges also sit on the panel throughout the season.
