The Top 18 face a mystery box challenge that includes cooking some of the finest shellfish in the world. The winner will receive a huge advantage moving forward, leaving the rest of the home cooks to compete in an elimination challenge, during which they must create a Gordon Ramsay classic. Then, it is up to the judges to decide who will leave the kitchen.

This week on MASTERCHEF, the home cooks head to Beverly Hills, CA, to take over the dining room breakfast service for The Belvedere restaurant at the iconic five-star Peninsula Hotel. After splitting into two teams, the cooks will make a variety of dishes for diners. The team that fails the challenge will have to face a pressure test and cook a perfectly battered fish and chips dish. It is then up to the judges to decide who will leave the kitchen.
