Five more comeback contestants return to the competition to try their luck again. A quarter-final place awaits those who outperform the others across two tough challenges.The first request from John and Gregg is for two outstanding plates of food - a main course and dessert that prove they have learnt from past mistakes. Some might be brave enough to recreate recipes from their past attempt. They will have one hour and 45 minutes to get creative and nail the brief. Nobody will head home after this round, but the judges won't forget dishes that leave a bad taste in their mouth.Next up, the comeback crew must show drive as they each design a dish that they would serve from a food truck. It will need to be a street-food gem to set socials alight and leave people queuing for more. This food style is right up the street of the guest taster - MasterChef: The Professionals 2019 champion, Stuart Deeley. Stuart's food is a celebration of what he likes to eat, so he'll be expecting to see real personality in the contestant's creations. Will they deliver a trucking treat that will tickle the taste buds? Or will their truck be towed back home?It's then crunch time, and the three who have impressed the most can celebrate with a place in the last quarter-final, with their dream of becoming MasterChef champion 2024 still very much alive.
