Your favourites are back for another crack at the coveted MasterChef title. Up for grabs tonight is this season's only immunity pin and joining them all week is chef extraordinaire, Gordon Ramsay.

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.

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.

Contestants must choose an ingredient they would like to feature in a dish, but they won't know the ingredient they must pair it with until they have locked in their choice. A Masterclass follows.

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.

After impressing the judges in yesterday's round robin relay challenge, the winning team are back in the kitchen cooking for immunity and a chance to be safe from the next elimination.
