The amateur cooks have one hour to recreate their signature dishes for the judges' first auditions, as the judges and nine past winners offer their support.

After giving out 18 aprons, the judges are searching for six more cooks to complete their top 24, and the chefs who were offered a second chance go head-to-head.

The ten losing contestants have to taste and identify all the 26 ingredients of Nigella's trifle before the elimination round where they will be using these ingredients.

On the first day of dessert challenges, the 12 contestants are tasked to cook their dishes in 30 minutes with ingredients from the Mystery Box chosen by Adriano Zumbo.

The contestants competing in the day's pressure test have just three hours to recreate guest chef, Brendan Wessles', lemon meringue pie from scratch.

The top 24 try to stand the heat in the kitchen, with 90 minutes and an open pantry to cook their dishes and impress the judges, focusing on hospitality.
