I'm not new to soap making (started in 1997) but I don't often make soaps with goat's milk in them. This particular batch I'm working on has Goat's milk and honey in it. I made the batch and all was well so I threw it in the freezer for 18 hours to make sure it didn't overheat and scald the milk. Took it out later and let it thaw. When I went to cut it it had gelled in the middle and scalded the milk and left the bars with brown dots in them. I guess I don't understand how it overheated while it was frozen? Any advice is welcome!
