While not as good as Rum Smoked Salmon (which I've never taken a picture of because I'm too anxious to eat it), this was still really good stuff.  Both recipes are again from Steve Raichlen's How To Grill book.  The mustard glaze has a couple different kinds of mustard, dill, brown sugar, and a few other spices.  Good stuff.

Just put on the grill with the mustard sauce and sprinkled with brown sugar.

All done.
