It's been over 48 hours. I got the one out of the silicone bread mold because I could just pull the silicone away from the soap and pop it out, but the ones in the tupperware containers are stuck in there! What do I do?
Try putting the mold in the freezer for about 30 minutes, take it out and let it warm up a bit and then try getting it out.
I've done this several times and it might take several tries but eventually it works. One of them I ended up smacking several times on the counter before they popped out.
Ack! How frustrating...I've read to place it in the freezer, then once very very cold to dip the bottom in some warm water and it should slide out. Good luck!
I haven't tried tupperware, but I got a loaf stuck in a wooden mold once by using a bad liner choice. I ended up freezing it, and then turning it upside down and hitting the bottom several times with a mallet.
Hope it helps!
