I've had this happen. Now, I warm my FO before adding it to hot soap. For this batch, can you get it out of the foamers and into a mason jar? I've been able to reclaim around 75% of a batch after it seized by putting the mason jar in a pot of water, bringing it to a boil, covering loosely with foil, and letting it cook for a couple hours. Make sure the level of water is just above the level of soap. After a few hours (2-4), screw the lid on your mason jar and blend the soap. You can put it in a cooler so it cools slowly. There's still going to be goo on top, but there will also be liquid soap on the bottom. I'm so sorry it happened!!
