I cooked cedar planked salmon last night on my kettle for the first time ever. I marinated the fish in italian dressing for a few hours, at the same time soaked the cedar plank in water for a few hours. I used Royal Oak lump, set it up for indirect heat. Once the coals were rolling, I placed the fish on the cedar on the grate opposite side of the coals. Cooked for about 35-40 mins...No idea what my temps were.. top and bottom vents were about half open. Once it was flaking w/ a poke from a fork, I removed it. Best fish I have ever had in my life. IDK if it was the marinade, the cedar or the lump ..or a combo of all the above, but gosh...it was delicious.
