Overview: The Top 12 enter the official Junior MasterChef kitchen for the first time, and learn about the points system. They start with a Mystery Box Challenge. Within the box are ingredients like chocolate, prawns, lemon and eggs. Except for sandwiches, anything can be made. The second test is an Invention Test with a “Pie and a Side” theme. All the young cooks amaze the judges who find awarding the points very hard to do.
