It's the third week of the heats, and five ambitious chefs from across the country begin their bid for the title with the first challenge - the Signature Dish Test. The professional chefs have just one hour to cook a stunning plate of food that truly showcases their talent. This could be their only chance to impress the judges as after the test, one chef will be sent home. Next, the remaining four chefs face Monica's Skills Test. Monica and Gregg ask each chef to showcase their pastry skills by making Monica's version of the French pastry, millefeuille. They must use their culinary skills and knowledge to first create caramel tuiles before using them to build a perfectly formed millefeuille with creme patissiere and raspberries, all in just 20 minutes.
