@Shea posted:Hi, wondering if 'old' royal icing is more likely to crater than 'fresh'. I used some RI that had been in fridge for a few weeks for some transfers and they cratered badly. Used thick icing. Did not use fan/dehydrator. Will try that today. But the cratering was so pronounced, not sure that will help? Will also make fresh batch of RI to compare. Thanks, Shea
Probably - if the icing isn't freshly beaten or the egg white protein ages/denatures with exposure to air, then the icing will have less stability.
