i used http://www.sweetsugarbelle.com/blog/2011/04/royal-icing-101-or-all-roads-lead-to-rome/ this recipe to made royal icing to make sugar cookies which i need to deliver tomorrow... and THE ROYAL ICING IS RUBBING OFF.......

I have always used wilton royal icing recipe and it works great but this time i gave try to a new recipe.... (foolish me)

please help me.... anyyyyyyyyyyyyyy remedy.

I have outlined my cookies and filled them half.... and after drying when i touch them the royal icing is rubbing off.... colored icing sugar is falling down ((((((((

Sorry to hear this but I would start the icing again.

Looking at the recipe, I don't know why it wouldn't set up unless there is oil somewhere. Are you sure everything is grease free? Check you extracts and colorings if you used them. I had a student once that accidentally used candy coloring (which is oil based) in her royal icing.
