Oh yay, thank you! Now I have a name for it! I remember a discussion with a young man (from South Africa, I believe) who was saying he was making what he called fudge (and now I'll know it's tablet :)) by boiling condensed milk in the can, fell asleep, and somehow it exploded. I can't even imagine how that could happen unless you didn't cut the top off, first, which would be in the 'too stupid to live' category. Well, perhaps he just meant it boiled over very badly. Let's hope, hm?
