Preparation

• In a small bowl, combine the sugar, salt, and pepper.
  Place the salmon fillets in a shallow dish, and sprinkle the mixture over each fillet. Turn the fillets over. Cover dish with plastic wrap, and refrigerate for 1 to 3 hours.
  Line a 10-inch round cast-iron skillet with aluminum foil.
  Cut a 2-inch hole in the center where the wood chips will be placed in direct contact with the bottom of the skillet.
  Heat the skillet over high heat until very hot, about 3 to 5 minutes.
  Line a heavy lid to fit the skillet. Brush the salmon fillets with the olive oil.
  Arrange the wood chips in center of hot pan. Place a wire rack with 1-inch high feet in the hot skillet.
  Arrange the salmon fillets on the rack. Cover tightly. Reduce the heat to medium. Smoke the salmon fillets for about 10 minutes.
  Test the inside of fillets for doneness.
  Serve at once or refrigerate and serve cold.
