Gingerbread (inspired) Houses
These may be more like Hanzel and Gretal Christmas-themed houses. This year we went with Gwen's idea of just using hot glue rather than scalding melted carmalized sugar to build them (awesome idea it turns out), so I think they are also becoming increasingly less edible as the years go on.
Oh well though, since the kids' building skills are increasing, so the houses are getting taller and more uniquely shaped and the kids are finding more and more ways to attach insane amounts of candy to their structures.
Really, I'm not so sure a few pieces of hot glue are any worse for you than approximately 45 pounds of straight sugar anyway.
