Peppermints
Those well acquainted with Ronald Weasley knew that he had a very sharp sweet tooth. Every kind of sweet appealed to him (accept of course the candy- coated insect type) sugar quills, rich chocolate cauldron cakes, fizzing licorice, and butterscotch wands were some of his favorites, but above all others, he loved peppermints.
The previous Christmas, his sister-in-law, Fleur, had given Hermione a three-in-one bottle of shampoo/body wash/ bubble bath. Ever since, that's all his love has ever used. Sometimes at night, well, most nights, he would roll over and smell her minty hair. She never really knew how much he loved that scent on her.
Whenever she went away, to see her parents, take a business trip, or merely getting up before him for an early day at work, he found himself with an insatiable craving for peppermints.
