Fool that I am, one evening recently, I found some honey that had hardened into crystals in a plastic jar and I put it on the stove in a (beautiful) stainless pot on a trivet almost full of water. I turned the heat on low and promptly forgot about it..
What a mess I found the next morning! I have managed to extract all the burnt honey, and some of the burnt plastic, but by no means all. Any suggestions would be much appreciated.
