So today I am smoking salmon for the first time. And using Alder from Fruit-a-wood also for the first time. I split a nice 1 3/4 ounce piece into two so the lid would close. Salmon in at 160. Got wispy smoke around 140, and by the time it reached 160 zip, zero, nada. Well I let it go. At a time of 0.6 I opened the smoker and pulled the box, very little char. Rearranged the wood and put a torch to it for maybe 5 seconds, closed it up and smoke. But I think my fix came too late into the process. We shall see.
