I made some of this when I was a teenager. You remove the seeds from the marrow and fill it with brown sugar. Then you hang it in a pair of tights and put a bowl underneath to catch the liquor. It was the most disgusting thing I have ever tasted (among things that are meant to be tasted, anyway).
I place my curse on Snorgle by stating definitively that she simply has to be right.

oh chalky...
