Brine: Place the pieces of salmon in a medium bowl with the brown sugar and kosher salt. Mix well. Cover and refrigerate for 2 hours.
Rinse: Remove the salmon from the fridge and rinse under cold water to remove the sugar mixture.
Air Dry: Pat the salmon dry with a paper towel and place the pieces skin side down on a baking rack over a sheet pan. Refrigerate uncovered for 2 more hours.
Heat Grill: Heat your smoker to 250F degrees with an indirect heat zone.
Make Glaze: In a small bowl, combine the maple syrup and hot sauce.
Smoke: Place the baking rack of salmon on the smoker. Cook for 45 minutes, basting with the syrup every 15 minutes. Cook to an internal temperature of 140-145F degrees.
Notes
I have done my best to estimate the nutritional value of this recipe. The sugar and salt are rinsed off before the salmon is smoked, so you only end up with a fraction of those ingredients in the final dish.
