Contestants faced a Mystery Box filled with a range of uncommon ingredients (including achacha, sorghum, sugar ants, New Zealand yams and Armenian cheese), and with 60 minutes to cook with ingredients they had never used before, the top three chosen were Billie, Jessie and Rose. Rose won the advantage in the Invention Test and chose to cook an Asian protein dish with 45 minutes to cook, meaning contestants had no access to any dairy or European ingredients. It was Jessica, Jessie and Sara whose inventive takes on Asian flavour won them the chance at immunity. Rose, despite having the advantage, misfired on her dish. The subtlety of her egg was overpowered by spices. She was joined by Matthew and Reynold in the Bottom 3.
