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.

Contestants face an off-site challenge at George Calombaris' Hellenic Republic restaurant. Divided into two teams, they must prepare a three course feast for 120 guests to avoid elimination.

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

Three contestants prepare popcorn-based dishes for the chance to compete against Braden White for an immunity pin.

A féte in Negella Lawson's name is held and the contestants are split off into three teams. The teams must prepare one savoury dish and two sweet dishes to sell, with all proceeds donated to the Royal Children's Hospital.

The bottom three from the invention test face the elimination pressure test. Contestants are given just over three hours to recreate UK chef Jason Atherton's quail afternoon tea dish to avoid elimination.
