Step 1

Rinse the fish fillets and place them in a shallow glass baking dish. Drizzle olive oil over the fish and season with garlic and rosemary. Rub the seasonings into the fish. Cover and refrigerate overnight.

Step 2

Dissolve the curing salt in the water and pour into the dish with the fish. Let it marinate for 15 minutes per half inch of thickness.

Step 3

Meanwhile, prepare your smoker for a four hour slow burn using charcoal. The temperature should be at 150 degrees F (65 degrees C) before you get started.

Step 4

Remove the fish from the brine and discard leftover liquid. Place each piece of fish onto a small piece of aluminum foil - just big enough to hold the fillet, and season with pepper to taste. Place them on the rack in the smoker. Sprinkle a handful of the soaked wood chips over the coals or place in a heat box. Cover and allow fish to smoke for 2 hours, adding more wood chips as needed.

Step 5

Increase the heat in the smoker (add more charcoal) to 200 degrees F (95 degrees C) and let the fish smoke until the internal temperature of the fillets reaches 165 degrees F (72 degrees C). Remove from the smoker and let rest for 20 minutes before serving.
