Gingerbread was firm but 12 hours later all soft
I am hoping to find some advice. I have made the parts of the gingerbread house and whilst it was nice and firm over about 12 hours it has now gone all soft and I haven't assembled it yet. I assume it will collapse if I assemble it now. Is it best to store in a tin as I am sure it went soft when I did that last year so I~ left it out this time and it still went soft!
