A nice use-case seen on the recipe website "Marmiton" is a widget to ajust ingredients quantity to the target number of eaters.

You can see it here[1] for example, "Ingrédients / Nombre de personnes", lower in the right column.

This implementation looks better than the ones commonly found on German recipe sites. As soon as you start adjusting they show you "3/8 pinches of salt" or "5/6 eggs".
