Smoking your own chicken and cheese really amp up the flavors of this dish. If that isn't an option, a purchased rotisserie chicken and smoked cheese will do.
I followed this outline
for cold-smoking cheese in an electric smoker. First time was not the charm. But it was worth the efforts.
The chicken was rubbed with Tonguespank
Smokey Bourbon, which adds some heat. Alternatively, add a dash of cayenne to the roux.
