第 17 季，第 6 集: Padma gets a real rise out of the chefs when she tasks them to make a Quickfire dish without any All-Purpose flour. Instead chefs must work with alternative flours from Blue Corn and Buckwheat to Coconut and Hazelnut. James Beard Award-Winning Chef Chris Bianco serves as the guest judge for the Quickfire Challenge. Then, the chefs are whisked off to the famous Walt Disney Concert Hall to meet legendary conductor Gustavo Dudamel who is about to celebrate the LA Philharmonic's 100th anniversary. The Maestro inspires the chefs to treat their flavor profiles like musical instruments, each providing a counterbalance to the other. For the Elimination Challenge, the chefs serve Dudamel and members of the LA Philharmonic at award-winning Otium restaurant along with Padma, Tom, Gail and Guest Judge, Bocuse d'Or finalist Timothy Hollingsworth.
