The top three contestants from the invention test must make a filled pasta with a matching sauce. The winner will enter a cook off for immunity against guest chef, Jake Kellie.
The hopeful chefs suit up and show up for Marco Pierre White Week. With 75 minutes ticking away, they use the ingredients from Marco's mystery box of ingredients.
Split into three teams, each must prepare one savoury and two sweet dishes to sell at a fete in honour of Nigella Lawson with proceeds donated to the Royal Children's Hospital.
It takes 20 ovens, miles of stainless steel, an arsenal of appliances and knives that chop, cut, slice and dice, to discover the best amateur chef in Australia.
Contestants have 75 minutes to create a delicious dish based on Nigella's divine indulgences. The top 3 will have a chance at immunity while the bottom 3 face elimination.
