The chefs must choose between a meat-and-two-vegetables dish or a risky mystery box challenge.

Two teams, aided by mentors Matt Sinclair and Sashi Cheliah, must cook an entrée and a main course dish for thirty diners.

The contestants are split into two teams and must cook three courses for 70 people with Marco Pierre White running the pass.

The winners of the test and mystery box face off against each other in round one, and the winner will go up against a professional chef.

The Top 24 contestants enter the kitchen for their first mystery box challenge to create a dish with ingredients chosen by 2015 winner.

Competitors team up and create a three-course menu for 100 people; Matt Sinclair guest stars to mentor the competitors.
