Leah, I prefer hot smoked salmon that has been cured, and forms the pellicle. Sounds like you are really happy with your results. I did it the same way for over 10 years. Then I did a test, with some pieces cured first, and other pieces just seasoned and smoked. I have cured ever since. It seems counter-intuitive, but the cured one was more succulent. Even though you panic when you see all of that water that got sucked out of the salmon in the dish after curing, the pellicle that is formed seems to hold in the fat during smoking. Plus the pellicle helps the smoke stick. From what I've read, water in salmon is not what makes the end product moist. It is fat retention. Try your own experiment for your next salmon smoke doing part cured, and part uncured, and see what you think. Here is my simple cure recipe:
Salmon - Hot Smoked
Salmon Cure:
1 part Salt
4 parts Brown Sugar
Heavily pack the cure on all sides on the salmon in a glass or food-safe dish. Cover and refrigerate for 8 hours. There will be a lot of liquid in the dish after curing. Thoroughly rinse cure off of salmon. Dry on a rack for about 3 hours to form a pellicle.
Set smoker to 170 degrees. Smoke until Salmon internal temp is 130-135 degrees. Many recipes say internal temp should be 145, by I think the salmon is not as soft and moist.
