Gingerbread Exchange Community

Thanks for the wonderful tip Adam!  You always have such helpful and useful information... perhaps from your years of experience! 

Something I've wondered... several years ago my husband and I both constructed a gingerbread house.  My house was covered in frosting and candy (well duh!), and his, was based more on architectural design and had no extra frosting/candy.

The only thing common in these two houses was that the same dough was used, the same recipe for windows (hard candy), and the same humidity level.

A few days after constructing/decorating, my windows melted and his did not.    The difference between the two?  I had decorative Royal Icing around every hard-candy window, and he did not.  I've wondered if the extra liquid contained in the Royal Icing affected the hard candy windows, as the Royal Icing dried (and the fluid in the frosting had to go somewhere?). 

Thoughts anyone?
