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 contestants' dessert skills are put to the test, and one chef goes up against guest chef Victor Liong.

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

Former contestants return to the MasterChef kitchen for the chance to win themselves a place back in the competition.

Contestants have 75 minutes to create a delicious dish based on Nigella Lawson's divine indulgences. The top three will have a chance at immunity, while the bottom three face elimination.
