Rinse the salmon and pat dry. Set aside.
Mix the dry brine by thoroughly combining 2 tbsp salt and 2 tbsp sugar together and set aside. Kosher salt has a much bigger circumference than table salt. if using table salt cut the amount by half.
Cover your cutting board or countertop with a long piece of cling film. Sprinkle half the brining mixture over the center of the cling film. Leave a 2-inch border free of the brine mix.
Roll the salmon portions in the brining mixture making sure that all sides are coated. Place the salmon skin side down (skin is facing the board) sprinkle the rest of the brining mixture all over the fish portions.
Seal the salmon by creating a tight parcel expelling as much air as possible. Lay the salmon flat on a plate or in a container and refrigerate for 2-4 hours. The brine will draw moisture/liquid from the fish, which is natural. Note: If it’s not put on a plate or in a container large enough, the liquid drawn out of the salmon will leak out into your refrigerator. Salmon must lay flat.
Meanwhile, get your smoker ready. Fold the heavy-duty foil into half and place it into the bottom of the wok. Twist the foil to crimp the edges to form a rim, creating a disposable tray that fits into the base of your wok or pot.
Sprinkle the sugar over the base of the foil tray, then the rice, and then the tea. Gently mix to incorporate. Set aside for later use.
Once the salmon has been brined, remove it from the refrigerator. The next step is very important for the salmon’s taste profile. Rinse thoroughly under cold running water. Remove all traces of the dry brine and liquid extracted. Failure to thoroughly rinse the salmon will make it very salty and or overly sweet when smoked.
Pat with kitchen paper so it is completely dry. Brush the skin side of salmon with a little oil to prevent it sticking to the trivet or rack. DO NOT BRUSH THE SALMON ALL OVER WITH OIL. Put the salmon on the smoking trivet or rack, then place that on a plate large enough to hold it. Allow to air dry uncovered in the refrigerator for 30-60 minutes.
During that time a sticky layer called the pellicle will form over the surface of the salmon. The pellicle brings many favorable things to smoking fish and meat. By far the biggest is that it helps to maintain moisture and allows the smoke to stick to the fish or meat.
When the salmon has finished processing, remove from the refrigerator, and set aside.
With the tray of smoking aromatics, centered in the wok or pot turn the heat to high. Leave the wok or pot uncovered for now. It can take 3-5 minutes for it to begin smoking. What you will see first is the rice and the tea gently moving in little puffs. This indicates that it is getting ready to smoke.
Soon after you will see puffs and wisps of white smoke. When you first start seeing the smoke forming immediately place the trivet or rack with the salmon into the wok, and cover with the tight-fitting lid. There needs to be 3-4 inches or more of space between the smoking aromatics and the salmon on the trivet.
IMMEDIATELY reduce heat to low. Set a timer for 8-12 minutes depending on the thickness of the salmon portion and the desired doneness.
Do not lift the lid to peak, because you’ll release the smoke and heat. You will know that your salmon has cooked, by its golden color and the white streaks or dots of albumin that has developed. Alternatively, you can test with a thermometer for your desire doneness or with the tip of a paring knife.
Immediately, remove the salmon from the smoker as it will continue to cook with residual heat and can overcook the fish. Garnish with sesame seeds and chopped parsley if desired.
