What is a nappe test in sauce making?

• A. The sauce should be poured as a thin film.
• B. The sauce should coat the back of a spoon and leave a clean line when drawn.
• C. The sauce should be transparent and run off the spoon.
• D. The sauce should be thick enough to stand on a plate.

Answer: (B)

The nappe test is about the sauce’s thickness and how well it clings. When you dip a spoon into the sauce and lift it, the sauce should coat the back of the spoon. If you draw a line with your finger along the edge of the spoon, the line should be clean and distinct, showing that the sauce has just the right body to hold its shape but still flow slightly. This level of viscosity means it will cling to food and glaze surfaces without running off. If the sauce pours as a thin film or runs off the spoon, it’s too thin. If it’s so thick that it doesn’t form a smooth coat or it stands in a heavy blob, it’s too thick. The described test—the coating and a clean line when drawn—best matches the correct behavior.
