So, I smoked up some Salmon fillets today on my Model #2 - first attempt at smoking fish. Set the smoker to 165'f with 2oz of wood in a chunk. The temp of the salmon rose fairly quickly until about 120'f or so, then slowed down dramatically. After about 3+hrs or more the temperature was reading 143'f, but didnt appear to be climbing any higher - not much steam/smoke was coming out of the smoker, so I decided to check on them. They looked a bit tough and overcooked, so I pulled them. They were indeed a little dry/overcooked. Not sure if I did something wrong or not? If I cedar plank smoke these same fillets on a grill they come out nice and juicy. Additionally, the block of wood was charred but not burned all the way to ash - probably about half of it was remaining. Perhaps I should have used chips or broken up the single chunk?
