Chef Marco Pierre White takes over the MasterChef Kitchen with a unique challenge. Home cooks face limited gas, electricity, and a mystery box containing just 250 ml of water. In this 90-minute challenge, the first 15 minutes have no gas or electricity. The following 30 minutes offer only electricity, then 30 minutes of gas, and the last 15 minutes both are available. The best dish wins an advantage for next week, while the top 4 are saved for the week.
