Heat six opens with four more professional chefs from around the country facing the infamous Skills Test under the watchful eyes of judges Monica Galetti, Marcus Wareing and Gregg Wallace.The first test is set by Marcus. Two of the chefs must prepare and cook sea bream served with couscous and a red pepper mayonnaise. The other two take on Monica's test. They need to prepare crepes served with a chocolate hazelnut spread, berries and chantilly. With just 20 minutes to complete their tasks, they need to work quickly while executing the dishes perfectly.Then they return to the kitchen to cook their Signature Dishes. They have one hour and 30 minutes to prepare a main and a dessert that demonstrate both technical ability and ambition. This is their chance to rectify any mistakes made in the Skills Test and showcase delicious flavours before the judges decide who will be sent home and who will make it through to this week's quarter-final.
