I should like to mention that sugar should NEVER be fed to birds, unless they are hummingbirds. Hummingbirds do not eat suet. Sugar is extremely dangerous for birds. They are not able to process it and so contract acute diarrhoea and become so emaciated that they die. I recognise that the recipe isn't yours, but perhaps you could add a note of caution?
