The Great Cookbook Challenge with Jamie Oliver

Just five cooks remain in the battle to win a cookbook publishing deal with Penguin Michael Joseph. This week, the focus is on the look of the dishes that the cooks must prepare. Jamie Oliver sets the first challenge, in which one of the country's most divisive vegetables, the Brussels sprout, is the key ingredient in a dish that the cooks photograph on their phones.

The remaining contestants face two challenges in the semi-final. First, they must cook in front of the judges for the first time in a live cooking demonstration. After this, they must prepare a lavish meal to be photographed, producing a visual feast that looks good enough to go in a double-page spread of the cookbook they hope to produce.

Jamie Oliver hosts the final of the quest to find the next big name in cookery. Just three cooks remain, each needing to prove to judges Louise Moore, Jimi Famurewa and Georgina Hayden that their book idea is the one to seal the deal. For their final challenge, the cooks must present their book concept and their range of recipes to representatives of the book buying world. As well as designing the front cover for their potential book, they must cook a feast of six very different dishes to represent the range and ambition of the recipes that will feature within their book's pages.
