Hi, I am looking for an movie about some kids in a british boarding school, and the boys have made a secret cooking club, where they bake and make food because the food that they get is quit awful. And later on the girls of the school join in on the club. And now this is the one thing that really stand out with this movie. some of the boys and girls fight each other and then the winners takes trophies in the form of there opponents shirt or jakket buttons, and I think that they also make a treasure chest with there winnings. But none the less, I have been aching to see this movie again for a few years now, so I hope that someone can help me out with the name of this movie. And thank you for you're time.
