The excited members of the Top 20 arrived for their first day in the MasterChef kitchen. Their first task: a Mystery Box Challenge. Each box contained 12 eggs, which all had to be used to create up to two dishes in 80 minutes. Gary revealed that the best six dishes would be tasted and points awarded to the best three. Lily won the challenge with her frittata and pavlova, Jack placed second with his Victoria sponge, with Gracie taking third with a chocolate cake and salmon crepes. George made a spectacular return to introduce the second, Greek-themed challenge. The contestants had 50 minutes to prepare a Greek dish using spatchcock, lamb or squid as the main ingredient. Madi’s fabulous lamb dish took the win, Jack again placed second with his stuffed squid hoods and Indigo secured third place points with her Skordalia spatchcock. At the end of day one Jack was sitting pretty at the top of the leaderboard.
