It's the last week of heats and seven more hopefuls need to pull out all the stops to prove to judges John Torode and Gregg Wallace that they have the potential to rise above the rest to become MasterChef 2018 Champion. Their first challenge is to invent and then cook one dish using anything from the market. This time, the featured ingredients include quail, chorizo, bone marrow, cod and squid. After tasting all seven dishes, John and Gregg decide which four cooks are good enough to stay. The four remaining cooks now have one more challenge standing between them and a quarter-final place. They must cook two courses that will excite not just John and Gregg, but also some of MasterChef's most inspiring winners and finalists, who return to judge the food of this year's new contenders to the throne. After the four hopefuls have cooked, John and Gregg will decide which three contestants deserve to take the next step in the competition and go through to Friday's quarter-final.
