I made a batch of this last night and did I ever screw it up.  I didn't cook the sugar and cream long enough and it didn't harden like it should have so while it's still eatable, it's better to eat it with a spoon than try to cut it in squares. 

 

Am going to make another batch this weekend and see if I can't do it right this time.  You have to bring the cream and brown sugar to just the right boil before it turns out good and it's not that hard to do but I was in a hurry and just thought it was ok when it wasn't.
