This is the king of all man drinks... A Rusty Nail !
Must use a worthy scotch, so as not to insult the Drambuie. Not too good - no need to go with a single malt, but not the cheap stuff either. Personally, I find that Chivas does the trick just right.
Pairs well with most any stout, sweet, full bodied Maduro or even a good Oscuro. LFD comes to mind!
Enjoy...
