Ah that makes sense! Thanks Because the stupid water was boiling it was somehow coming up the sides between the saucepan and the bowl, it would have easily gotten in the chocolate. I've never actually tempered chocolate before, but I'll give that a go

I reckon I might have a go without the wooden spoon too, it didn't seem to be helping things. It definitely wasn't on the heat for very long, but as soon as the water started boiling it went down hill!
