Kelly Clarkson drops into the "Top Chef" kitchen for a Quickfire based on her new movie, "Trolls: World Tour," where the chefs are tasked with combining colorful ingredients from six different musical lands to make one delicious dish.

The final five travel to Italy, where the chefs must make an aperitivo for 30 locals from the town of Lucca that pairs perfectly with a Peroni beer; then, they hunt the elusive white truffle which they must use in a dish for a Tuscan food festival.

With only six chefs remaining, the challenges get even more difficult, when pastry super-chef Sherry Yard awaits the all stars for a dreaded dessert Quickfire; chefs endure a blindfolded taste test to pick their ingredients.

The eight remaining chefs split into teams and are tasked with creating a Chef's Table restaurant concept, where they must serve a seven-course, high-end tasting menu to the judges and all-star panel.

The chefs honor the late, great Pulitzer-Prize winning food critic Jonathan Gold; using Gold's last guide list, the chefs fan out all over Los Angeles to sample the unique food trucks, mom-and-pop cafes, and ethnic cuisine.

In a head-to-head challenge, the chefs cook for guest judge Jamie Bissonnette; the chefs make dishes on a lean military budget at the historic Watertown Arsenal.
