O.K. So I am getting really frustrated. I have tried three times to use the Wilton gumpaste & fondant mold set. I am using fondant. The letters always stick & when I finally get them out, they look terrible. I have dusted the molds with cornstarch & also left the fondant overnight in the molds to firm up, but I still cannot get them out. I am gently using the releasing tool. Help! What am I doing wrong? I am about to toss this thing in the garbage.
Don't know the mold personally but i would try popping it into the freezer, should only need 10 minutes or so for it to get solid then it should pop out, do still cornstarch well.
Try to grease it with white fat
