Today's mystery box is selected by MasterChef Australia champion, Emelia Jackson. The three best dishes will be awarded an immunity pin that can be played at any time during an elimination cook.
The team arrive at Simpson's Gap and judges reveal the contestants must create a dish using a variety of foraged bush foods. The contestant with the least impressive dish will be sent home.
Yotam Ottolenghi presents his favourite flavour bombs - numbing oil, fenugreek marinade and chipotle peanuts. Each team must create a meal which needs to feature one of Yotam's flavour bombs.
The judges welcome the contestants to Martin Benn's opulent new Melbourne restaurant, Society. The pressure is on as they discover today's service challenge is also an elimination.
Contestants must choose an ingredient and cook it two ways, in a fast-food and in a fancy food application. The contestants with the three least impressive fast-food dishes will cook in round two.
