Finals Week continues, and just four cooks remain. Now they embark on a culinary adventure of a lifetime to Peru. Over the last decade, Lima, the capital, has led a food revolution that has popularised Peruvian cuisine around the world. Here the finalists face three challenges, guided by two of Peru's most acclaimed chefs. The first challenge takes place in Lima's major fish market Chorillos, where, in teams of two, they are tasked with recreating four popular iconic Peruvian dishes to serve to a group of local fishermen.
