Begin by slicing lengthwise each of your arctic char filets into 3 equally sized pieces. Tip: slice from the tail side of the fish, and keep each piece still connected at that end. When done slicing, begin braiding each filet then securely pin the loose end with a toothpick. Using the two braided filets, make a circle mimicking a wreath. Pin the two filets at each point of contact, then lather with oil. Mix your seasoning and thoroughly spread it out over the fish. Place fish in the fridge until ready to cook.
Preheat your smoker for indirect cooking at medium-low heat (around 300F).
Add two medium sized cedar planks to your smoker to preheat 2 minutes before cooking. Add the arctic char wreath onto the cedar planks and begin cooking. Cook for about 1-1.5 hours until the fish is 135F internal. Once done, pull off and let rest.
While resting, add a basting skillet over direct heat of the fire along with some lemon halves. Add all the ingredients for the Sriracha Butter, and let melt. Once melted, pull off fire.
Lather over your fish the Sriracha Butter sauce. Garnish with chopped scallions, charred lemons and enjoy!
