It's the last week of the heats and five ambitious chefs from kitchens across the country begin their bid for the title when they face their first challenge - the Signature Dish Test. With just one hour to cook a stunning plate of food that truly showcases their talent, the professional chefs must pull out all the stops to impress the judges. After this test, the judges must send one chef home. In the feared Skills Test, Monica asks the remaining chefs to prepare and deliver a cuttlefish dish in just 15 minutes.
