Gordon Ramsay greets 23 returning contestants and announces that they are splitting into 3 teams to take on a service challenge.

Eight cooks race against time to deliver two of Gordon Ramsay's dishes in a fight for the immunity pin.

Contestants must cook and elevate their favourite late-night snack for a chance to win immunity and see their creation added to Gordon Ramsay's new London restaurant's menu at 22 Bishopsgate.

Contestants are challenged to create dishes that feature a chicken or an egg. The one with the least impressive dish will be sent home.

Cooking legend Massimo Bottura presents his take on the classic dish, mac and cheese, for the elimination challenge.

MasterChef Australia champion Emelia Jackson sets the contents of the mystery box; the three best dishes will be awarded an immunity pin.
