Before 2010, the format featured three rounds: The Ingredients Test: the contestants were asked to identify a selection of ingredients or produce.

At least one contestant was eliminated after this round. The remaining quarter-finalists each produced a two-course meal in one hour.

The Choice Test: the contestants have 80 minutes to create a showstopping dish for the judges and a special celebrity food critic.
