A finished béchamel sauce should indeed coat the back of a spoon. This classic test, known as "nappé", indicates that the sauce has reached the ideal thickness. To check, dip a spoon into the sauce, then run your finger across the back of the spoon. If the line drawn remains clear, your sauce is perfectly thickened and ready to serve. This ensures a rich, creamy texture that’s perfect for enhancing your dishes.
