Although not as good as Chinook, it's readily available at Costco for a good price, and I think I finally nailed it, so here goes FWIW:
3 filets, total about 2.5 lbs.
1/2 C. Salt
1 C. Brown Sugar
1/4 tsp Garlic Powder
1/4 tsp Liquid smoke
Juice from one lime
4 Tbsp Molasses
1 Qt Water
Brined overnight, about 7 hours.
Smoked for 5 hours on the CS @150 - 160 deg. Started with 3 small chunks of 2 year old Alder, added 2 more after 3 hours.
Let set in foil wrapped with a towel for slow cooling, refrigerated overnight. Not salty, nice subtle smoke, and slightly sweet. This formula is a keeper!
