S17, E10: 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, made even more impossible when chefs must endure a blindfolded taste test to pick their ingredients. Then Michelin-starred Chefs/Restaurateurs Niki and Carole Lidi-Nakayama demonstrate a traditional Japanese Kaiseki meal, the ultimate in simplicity, restraint and precision. The chefs must make this formidable dinner for not just these Kaiseki masters, but in celebration of the Tokyo games with Olympic medalists Diana Taurasi, Rai Benjamin, Nastia Liukin, Ibtihaj Muhammad, Christian Coleman, Kerri Walsh Jennings and NBC Olympic Primetime Host Mike Tirico. The gold medal meal takes place at the iconic Los Angeles Coliseum with Padma, Tom, Nilou Motamed and Niki & Carole Lidi-Nakayama at the judges table.
