I have always used a dry brine for smoking the recipe I use is

2 1/2 cps brown sugar
1 cp white sugar
1/4 cp salt
1/4 cp pepper
1/3 cp johnnys seasoning or any other type
1/2 cp gallic powder

Smoke for 6-8 hours for cooking

or what I like to do is smoke for 1 hour then pressure cook for 100minutes at 11 pounds.

Canned smoke salmon is like gold.

good luck
