The top three contestants from the invention test must make a filled pasta with a matching sauce. The winner will then enter a cook off for immunity against guest chef, Jake Kellie.

2015's Masterchef, Billie McKay, knows exactly what this crop of aspirants are going through. Do you reckon she'll go easy on them when she picks the ingredients of the First Mystery Box?

The contestants from the losing pub lunch challenge team must correctly name an ingredient to avoid the elimination cook-off challenge, as the contestant with the least impressive dish will go home

This challenge is all about the pub lunch. The contestants are split into two teams and must cook three courses for 70 people with Marco Pierre White running the pass.

Split into three teams, each team must prepare one savoury dish and two sweet dishes to sell at a fete held in honour of Nigella Lawson with all proceeds donated to the Royal Children's Hospital.

This mystery box challenge has been chosen by the viewers. Contestants have 75 minutes to create a dish using at least one ingredient chosen by the viewers.
