How to Smoke Salmon (Brined and Hot-Smoked)

Pour 3 cups of cold water into a medium pot. Add 3/4 cup of packed light brown sugar and 1/3 cup of coarse sea salt. Use a peeler to take the zest off one orange and one lemon, staying shallow so you skip the bitter white pith, and drop the zest in.

Bring it up to a boil and stir until the sugar and salt fully dissolve. Kill the heat and add 4 cups of ice. That chills the brine fast so you can pour it over cold salmon, and it dilutes the sweet and salty edge at the same time. Keep the brine simple. You want every bite to taste like salmon first, not like a spice cabinet.

Work with a whole side of salmon, skin on, and use a sharp non-flexible boning knife. Bigger, evenly thick pieces cook up more tender, so trim off the thin tail end and the belly strip where the fillet tapers down. Save both for another meal.

That belly fat is worth holding onto. Fat is flavor, and a quick sear of the belly with a little oil, salt, and pepper is a treat on its own. On the back edge, curve the blade and follow the pinbone line to trim it clean. Leave the skin fully attached. It acts as a barrier that keeps moisture from escaping the bottom while the salmon smokes.

Lay the trimmed side in a non-reactive dish. Ceramic, stainless steel, glass, or plastic all work. Avoid reactive metal like bare aluminum. Pour the cooled brine right over the top.

If the salmon floats and pokes above the liquid, flip it skin side up. The flesh stays down in the brine where it belongs, and the skin can ride on top. Cover with plastic wrap and refrigerate for 12 hours or overnight. Here's the rule on overnight: brine in the morning, cook the next morning. Do not stretch it past 24 hours or the fish turns way too salty.

Pull the salmon out of the brine and set it on a parchment-lined sheet tray or a platter. Give it a quick rinse under cold running water, both sides, to wash off the surface brine.

This takes a few seconds and it matters. Leave that concentrated brine sitting on the surface and the finished salmon reads too salty. A short cold rinse pulls the seasoning back into balance without washing out the flavor you built inside the fish.

Move the salmon to a sheet tray fitted with a wire rack so air can move all the way around it. Pat the surface dry with paper towels for a minute or so, dabbing gently rather than scrubbing.

What you're building here is the pellicle, a thin tacky skin that forms as the surface dries. It seals things in and, because it's a little sticky, it grabs the smoke and pulls in that flavor and color. After patting, let the salmon sit and air-dry for about two hours. It feels like a long wait for a small step, but this is the part most people skip and then wonder why their smoke doesn't stick. Don't skip it.

With about 30 minutes left in the drying time, load your hopper and fire up the smoker at 150F. Once it's up to temperature and the salmon has had its full two hours to dry, brush the grates with plenty of neutral oil so the fish releases cleanly.

Set the salmon on an upper rack, away from the hot firebox, so it takes on smoke without cooking too fast. Push a probe thermometer into the thickest part of the fillet and set your target to 140F internal. A pellet smoker runs humid inside, so there's no need for a water pan. Expect roughly two to two and a half hours at this temperature.

After about an hour of smoking, build the glaze. In a small saucepan combine 1/2 cup of packed light brown sugar, 1/2 stick of unsalted butter, and 1 tablespoon of soy sauce. Halve the orange and lemon you zested earlier and squeeze in all their juice, catching seeds with your other hand.

Bring it to a boil over medium heat and stir until the sugar dissolves. Brush heaping loads over the salmon, then keep basting every 30 minutes as it cooks. Around the two-hour mark you can bump the smoker up to 200F for a little extra browning. If you see white albumin creeping out, that's normal, but if the fish gets covered in it, slide the salmon farther from the heat.

When the probe hits 140F internally, the salmon is done. It should look like candy, with a glassy sheen over that deep mahogany top. Pull the thermometer and lift the salmon off with a wide fish spatula or gloved hands, since it's delicate and warm.

Rest it on a lined sheet tray for 10 to 15 minutes to settle. Brush on one last coat of glaze right before serving. Eat it warm as is, or cool it down, wrap it, and keep it in the fridge for seven to ten days. It also freezes well for up to six months, so a single side stretches into a lot of good eating.
