First time making jelly. The article says "When the boil can't be stirred
down, add the pectin." What do they mean by "can't be stirred down"? Too
thick to stir?

And, how much of a cleanup horrow is this going to be, considering all the
boiled sugar? Let's assume I don't leave the kitchen to take a phone call
and let the whole mixture burn or blow up. :-)
