Sir Alan sets the teams the task of manufacturing sweets to sell at one of the country's top tourist attractions – London Zoo. Their target market are the toughest consumers in the world: parents and children. It's Ghazal and Adam's first turn as team leaders, and they and their budding Willy Wonkas must decide if their sweets should appeal to health conscious parents or sugar crazed kids. Then the teams must do something special to stand out against the Zoo's star attractions – the monkeys, lions and tigers.

With over 3000 potential customers the teams adopt unique selling approaches – from the charm offensive to the hard sell. But when one team tries to stretch the truth it lands them in trouble. In the boardroom, Sugar is not so sweet to the losing team – and one of them is about to get fired.

The ten remaining candidates face their toughest sales challenge yet, as they have to sell British food to French people in France. With market stalls laid on by Sugar in a northern Gallic town, the teams spend a day sourcing produce in Kent before crossing the Channel to flog their British grub to the fussiest foodies in Europe.

Paul has a brainwave about an old army cooking technique he thinks will give his team the advantage, while on the other team Lohit spends his time trying to calm the conflict brewing in his troops. With hardly a word of French between them and centuries of gastronomic prejudice to overturn, will the teams sink or swim across the channel? In the boardroom, Sir Alan is stunned by the results, and a shocking revelation is made by two of the candidates.
