This week the task is a creative one: each team has to come up with an advertising campaign for a new hi-fi product, and the item is one of Sugar's own, a prototype he wants to launch in America.

The candidates travel to find an agricultural product that can be transformed into a commodity and sold for profit at a City farmers' market. One team picks fruit from the hedgerows of Berkshire to make jam, while the other buys blue cheese and venison to make soup.
