Make the Brine: In a large bowl, whisk together brown sugar, salt, and cold water until the salt begins to dissolve.
Brine the Salmon: Place salmon in an airtight container and pour the brine over top, ensuring it’s fully submerged.Refrigerate for 12 hours, then remove, pat dry, and transfer to a drying rack. Let it dry uncovered in the fridge for another 8–12 hours. (You can use a fan to speed things up.)
Smoke the Salmon: Preheat your smoker to 170°F. If it runs hot, add ice to the drip pan to keep the temperature stable. Add salmon to the smoker and smoke for 2–3 hours, until the internal temp reaches 130°F.
Make the Glaze: In a small bowl, whisk together mango purée and hot honey until smooth.
Baste & Finish: Once the salmon hits 130°F, start brushing with the glaze every 20 minutes until it reaches 145°F (about another 1–1.5 hours). For a caramelized finish, increase the heat to 400°F for the last 10 minutes.
