The show goes to chocolate heaven, as the cooks are challenged to produce sensational sweet and savoury spoonfuls containing chocolate, ranging from chocolate cupcakes to chocolate and Stilton tarts.

Simon Rogan, the chef behind L'enclume, one of Britain's best restaurants, shows the cooks how one man's trash is another man's treasure, as he challenges them to cook fantastic food using leftovers.

To progress to the semi-final, the six remaining cooks have to prove they can make exceptional food from the finest cuts of meat and from the 'forgotten cuts', like bone marrow and tripe.
