Smoked Mac and cheese with say.....fried catfish sounds GREAT!!!!!
BUT.............
(yes, that's a BIG but)
With smoked brisket and ribs and smoky beans or whatever else has been on the smoker for 12 hours?
Overkill if you asked me.
I am a flavor JUNKIE. I would have been the first moron to throw EVERYTHING including the salad in the smoker.
And YOU and ME might have enjoyed EVERYTHING smoked.
But mere mortals like SWMBO and your buddies and relatives?
Overkill.
I have learned from pushing the envelope and getting burned too many times.
CONTRAST is what wins.
If your protien is SMOKY, then the mac and cheese probably should have NO bacon or smoke. Nor should the cole slaw or whatever else. Your comment that it would have to be the "last" thing on the smoker leads me to envision a procession of smokiness.
