In the Mystery Box challenge, contestants were given a single egg and the challenge to create a dish making this egg the hero. The Top 6 (with one contestant from every row of benches) were selected and ranked, with Kylie's Poached Meringue the standout dish, over Mindy, Andy, Jules, Amina and Andrew, respectively. For the Invention Test, set by Rick Stein, the winning contestants, in ranking order, picked a type of seafood and a country to inspire dishes which their bench-teams would prepare. Stein was impressed with most team's ability to encapsulate the essence of their given countries cuisine, but it was Team Morocco (Jules, Alice and Tregan) who prevailed and won the opportunity to cook for immunity. Given Botargo to create a United Kingdom-inspired dish, Andrew, Dalvinder and Audra struggled with the unfamiliar ingredient and fell into the Bottom 3 and a Pressure Test.
