I am usung a 1/2 shell mold . Dollop of jelly then peanut butter ganache. I've been making them for 3 years now & suddenly the top where the jelly is collaspes in . also the face/inside curve of the shell starts to bloom. I do other chocolates in the same mold but no bloom. This bloom is also happening on the sides of a fleur d lis mold I use.
