In this week's Skill Drill, it's up to the chefs to take direction from their recruits, as contestants are working in teams to dictate to their mentors via headset the whats and hows of making a plate of lamb chops, potatoes and charmoula. The trick? The chefs can't use a recipe or see the finished dish they must replicate; they have only their recruits' commands and descriptions to follow as they cook.
