The boys at Repton periodically receive a package from Cadbury, a chocolate company. The package contains a variety of chocolate bars which the boys are to sample and critique in writing for the company’s research and development purposes. The boys all take this task very seriously. For
Roald, it spurs the realization that someone at chocolate factories must be in charge of coming up with ideas and testing new chocolate flavors. His experience in sampling Cadbury’s chocolates later informs his second children’s book,
Charlie and the Chocolate Factory.
