I got a brine recipe for smokin' Salmon from an ironworker long ago. Got's brown sugar in it and he used apple wood for the smoke. Man o' man it was good. Gotta find it.
I like the apple, that's what my last pan of smoke will be. Starting with alder, also put brown sugar in this for 1/3 of the total sugar, I have to be careful of balance because I also like to add honey and orange juice.
