In the first Mystery Box challenge of the season, the Top 11 duos enter the kitchen to find not one, but two boxes at their station. They lift them to discover one box contains sweet ingredients and the other, spicy ingredients. Each pair of cooks must combine the two boxes of ingredients to make a harmonious, MasterChef-worthy dish. The duo with the winning dish will get an advantage in the next challenge, while the duo with the worst dish will be out of the competition. (thetvdb.com)
