George sets up the Mystery Box Challenge for the nineteen remaining contestants to cook a dish with leftovers from his restaurant the Press Club. Emelia, Kira, Renae, Sarah and Colin were chosen as the top five with Emelia’s avgolemono dish that won the advantage. She chose to remove the proteins (including gelatine) from the pantry to cook the inventive dishes. This invention test was a struggle for some of the contestants but it was Tash, Brent and Sarah who delivered the top three dishes while the judges slam Jamie, Steven and Scott’s dishes, sending them to the Pressure test.
