Contestants compete in the Quarter Final challenge using ingredients chosen by loved ones, cooking off for a place in the Semi Final.

The bottom three contestants face-off in the elimination pressure test; they must recreate two of guest chef Ross Lusted's signature dishes in two hours.

The amateur chefs are tasked with cooking a dish using one ingredient from Marco Pierre White's mystery box.

The final three contestants must prepare two dishes to be served to 20 diners in a four-hour service challenge.

The competition goes to California for the week, where, armed with only a map, contestants track down mystery box ingredients from local shops.

After being split into teams, the contestants cook a three-course meal for 30 guests from two Melbourne restaurants.
