Overview: In the second heat of the week, four new professional chefs arrive ready and determined to cook off against each other in the MasterChef Kitchen in the hopes of making it through to the quarter-finals. Two gruelling challenges lay ahead of them. First up is the skills test. The first two chefs are challenged by Monica Galetti to French-trim a rack of lamb and cook a portion to serve with a mint pesto. The other two chefs take on Marcus Wareing’s test where they must fillet a plaice and prepare it with a chicken butter sauce and pickled radish. Then the four chefs return to the kitchen to cook their own two-course signature dishes. They have one hour and 30 minutes to cook up a main and a dessert that highlight their creativity, flair and personal style. Then Monica, Marcus and Gregg will send two chefs home, while two progress to the next round.
