Every once in a while. They're generally nothing more than sugar, gelatin, and corn syrup.

[ there's no nutritional value in them whatsoever, though she supposes that's what might make them such a treat - particularly to someone who's never had one.]

I like them in s'mores. They're - chocolate, graham crackers, and a toasted marshmallow. When I decide to indulge, I don't hold back.
