This recipe can be doubled, tripled, etc. for the amount of salmon you have:
3 Cups water
2 Tbsp kosher salt
2 Tbsp brown sugar
3 Tbsp maple syrup
1 tsp peppercorns - smashed
1 tsp soy sauce
2 Tbsp vodka (this is the only thing I would not double or triple, maybe just add 1 more tbsp)
Cut salmon into small pieces to your liking. Brine salmon for at least one day or even two. What we smoked today was just shy of a day. I like to use zip lock bags as less brine is needed and squeezing out the air aids in getting the brine into the meat. Drain and dry on paper towels. Lay pieces skin side down on a rack set over a baking sheet. Air dry using a fan blowing over the salmon for about 2 hours.
We smoked the salmon using charcoal and applewood at 140-160f for 2 hours. Half way through the smoking, I brushed honey on top of the salmon. Let cool completely and wrap tightly. The salmon should keep for up to one week in the refrigerator, or frozen for several months. I used my FoodSaver vacuum sealer to store the salmon.
