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.

Superstars Week kicks off with Nigella Lawson. Contestants must recreate Nigella's favourite dish based on her detailed description. With no ingredient list, recipe or visual reference to work from.

In today's two round challange, contestants must create dishes that feature a chicken or an egg. The contestant with least impressive dish will be the first 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 reveal today's elimination challenge is over two rounds and is set by cooking legend, Massimo Bottura. Massimo presents his take on the classic dish, mac and cheese.

Each team must cook the same six dishes within the time allocated. Each contestant on the team will cook one of the dishes and will be judged against the same dish made by the other two teams.
