Fan favourites return for another chance at the title where they compete to grab the season's only immunity pin.
Each team must produce a three-course meal for 120 guests. The judges reveal three ingredients: black garlic, ginger, and potatoes, and each team must feature one of the ingredients for each course.
Every contestant apart from the winner of the immunity challenge is up for elimination; the contestants feel the pressure to remain in the competition.
