The cooks face their first Mystery Box Challenge where the winner selects one of three international cuisines; some cooks get lost in translation.

A Mystery Box Challenge requires the cooks to work together and the winners give the assignments in the pantry challenge.

In the first team challenge, the remaining cooks work hard to honour firefighting heroes in a rib cook-off.

The teams use a fashion collection as inspiration for a fancy lunch; a surf and turf test sends one cook home.

Astronaut Chris Hadfield inspires the cooks for a Mystery Box Challenge. They must also prepare a gourmet meal using a specific set of ingredients in 45 minutes.

The remaining eight cooks take on intimidating nursery rhyme-inspired ingredients. They must use pig's head or grouper's head, beef shoulder or lamb shoulder, turkey legs or frog legs, and pig's trotter or chicken feet.
