Nine home cooks arrive for the second week of heats.Their first test is the Audition Round. Each must cook a signature dish, which John and Gregg judge solely on taste. Their three favourite dishes earn a MasterChef apron and immunity from having to cook in the next round.The remaining six contestants then get another chance to impress the judges and win themselves a coveted apron. If they cooked a savoury dish in the first round, they must deliver a sweet one now, and vice versa. This time, John and Gregg are in the kitchen witnessing their every move. The pressure is intense and the stakes are high as only four cooks can join the three already fast-tracked to the next round. For two, their MasterChef dream will be over.
