So this looks pretty good, but after 4 hours the cream puffs started falling off!! Does anyone know what could have caused this? I was thinking that maybe the wet raspberries moistened the sugar, or the cream puffs were too soft or too heavy, so gravity took over, but honestly I thought that dried hot sugar was like cement! I would appreciate thoughts if anyone has ideas. . . http://cupofsugarpinchoflove.blogspot.com/2015/12/crumbling-croquembouche.html
