Mystery Box Challenge: The home cooks were allowed to fill a Mystery Box with up to fifteen ingredients of their choosing. Gordon then asked them to give their ingredients to the cook in front of them. Thus, Christine wound up with Becky's ingredients, Monti ended up with Christine's Asian ingredients, Frank wound up with Monti's dessert box, Josh ended up with Frank's Italian ingredients, and Becky received Josh's southern-cuisine ingredients. Josh beat out Monti and Christine to win. Challenge Winner: Josh Marks. Elimination Test: Given three dishes made by Graham, Josh chose everyone to make his white tuna dish, being given a basket containing all the necessary ingredients. Graham told the contestants that they may improve upon his dish if they deemed it necessary. Christine had the best dish. Winner: Christine Hà. Bottom three: Becky Reams, Josh Marks and Monti Carlo. Becky was sent to safety, then Monti was eliminated. Eliminated: Monti Carlo.
