The Master Chef... But He Can't Taste?

Noah wants the title of Master Chef back. He cannot taste anything. He was the youngest chef ever to be spoken of as the next Master Chef, and the way to the top was open to him until the final of an international cooking contest. A rival from abroad tricked him there. Noah, sure of himself, took an experimental ingredient the man had poisoned and cooked with it. The judges collapsed after eating the dish. Noah tasted it himself and his sense of taste never came back. The country he cooked for was disgraced. His mentor, who had stood up for him and led the Gastronomic Alliance, was broken by what happened. Noah left the trade and lived as an ordinary man. Later a businessman moves to take over the restaurant that has taken Noah in, along with the people it shelters. Noah goes back to cooking to stop him, working from experience and what he remembers of flavors, and the businessman's move on the restaurant is only days from being complete.
