Hello, several weeks after I moulded some ganache filled chocolates, their shells collapsed. I have attached a photo that demonstrates the problem. I am not sure why this happened. My guess is that this is because the ganache filling dried and shrank thus either making the candy hollow or maybe the internal pressure got lower, I do not know... What did I do wrong? How to prevent this? Keep them in an air tight container (which I did not)? Or in a fridge (which I did not either)?
Thanks!
