Mystery Box Challenge: Alessandra Ambrosio joined the judges to introduce the challenge. The contestants had one hour to cook a dish featuring at least one of Latin American cuisine's staple proteins. After thirty minutes of cooking time, the judges also asked them to make a ceviche to accompany their dish. Fred, Sam, and Liz were declared as having the worst dishes while Evan, Michael, Shari, Nick, Bri, and Wuta were called to the front for having the best dishes of the night. The judges granted Shari, Nick, and Wuta immunity while the rest had to face elimination next episode. Challenge Winners/Immune: Nick DiGiovanni, Shari Mukherjee and Wuta Onda.
