With the teams complete, the competition is ready to begin. The first challenge kicks off with the theme of Comfort Food. The way the competition will work is in two parts. First, the four mentors will work with their teams in the Team Taste Test, in which each member of the team will create one spoon based on the theme, and then the mentor will select one spoon to put forward for judging by the guest judge.The guest judge this week is Gabrielle Hamilton, the chef and owner of Prune in New York City. Once Gabrielle selects one winner out of the four competing spoons in the Team Taste Test, the winning chef will gain immunity in the Blind Taste Test, the second part of this week's challenge.Gabrielle will then join the winning kitchen to assist the team of chefs as they prepare for the Blind Taste Test for the mentors. In the Blind Taste Test, the mentors taste each of the dishes blindly – they have no idea who prepared the dish or what they are tasting. Each mentor will then select their best taste, followed by their worst taste to determine which chefs will be sent home this week.
