In this first episode the cooks have 90 minutes to prepare their ultimate burger with at least two sides designed to showcase their individual personality. The second challenge tests the cooks' inventiveness and creativity with a key ingredient, and the cooks with the best burgers from challenge one get to determine the key ingredient choice for everyone. This time, the choice is between nuts and berries, and the cooks must invent a sweet or savoury dish celebrating the central ingredient. Based on their performance, the judges decide who is safely through to next week and who must cook again. At the end, one cook leaves the competition.
