It's the second week of heats, and seven more hopefuls need to pull out all the stops to impress judges John Torode and Gregg Wallace. This year sees the return of the MasterChef Market, stocked full of the best-quality produce from across the world. The challenge is to invent and then cook one dish using anything from the market. The featured ingredients include venison, chicken, parma ham, sea bream and pollock, and the contestants have an hour and ten minutes to dazzle the judges. After tasting all seven dishes, John and Gregg decide which four cooks are good enough to stay, while three are sent home. The four remaining cooks must cook two courses that will excite not just John and Gregg but also some very special guests - 2015's MasterChef finalists Tony Rodd and Emma Spitzer and champion Simon Wood. After the four hopefuls have cooked, John and Gregg decide which three contestants deserve to take the next step in the competition and go through to Friday's quarter-final.
