Each team must cook a three-course meal for 120 guests. The judges reveal three ingredients: black garlic, ginger and potatoes. Each team must feature one of the ingredients in each course.

It's the first mystery box challenge of the season and it's a tough one! The remaining contestants discover the ingredients have been chosen from all corners of the globe, by judge Melissa Leong.

Today the contestants compete in the ultimate BBQ challenge, cooking for a staggering 1200 people.The team who least impresses, will find themselves cooking in tomorrow's pressure test.

Teams must cook a three-course meal in a relay style cook. Each team member starts a course and after 20 minutes must swap to the next course. The most cohesive menu with the best dishes wins.

The judges reveal that each contestant's mystery box, contains four ingredients which they can barter with one another for. The top four dishes will see their makers cook for immunity tomorrow.
