Page 19 needs a correction. You can't have an untouched clean plate of food. Untouched means all of the food is still there. A clean plate means all of the food has been eaten. If you want to word it like that, consider using a synonym for clean like pristine. Then you could get across the point that not only was the food not eaten but left undisturbed and still as it was presented/served, since a fancy royal meal would have been arranged in an aesthetically pleasing way. Meaning it was literally left untouched.
