Today, eight more amateurs try to prove to judges John Torode and Gregg Wallace that they have the potential to be the 2017 MasterChef Champion. This year sees the introduction of the all-new MasterChef market - which is stocked full of produce from all around the world as well as a selection of meat and fish. The first challenge for the eight contestants is to invent and cook one dish using what's available to them in the market. On offer today are duck legs, ox tail, lamb mince, langoustine, cod and scallops.
