I tried Long_shots recipe and will never need another. I smoke mine on a Treager and use Hickory, apple and cherry for the best results. Mix brine and let it cool for about 20 minutes in fridge. Then add fish, I cut and debone mine so it's in nice 1x2.5 inch sizes. Leave it in the brine for 24 hours, smoke till done and enjoy. I've done fish and beef jerky with this bring, and it's perfect. We don't care for real salty brines so if you do enjoy the salt this may not be for you. I also added a 1/4 cup Ceyyene to the Beef Jerky for a sweet garlic tasting jerky with a bit of a kick.
1 cup brown sugar
3 tblsp garlic salt
1 or 2 tblsp soy sauce
1 tblsp minced garlic
1 tblsp black pepper
1 cup boiling water
