Hi! A couple of weeks ago I smoked a smaller (2 3/4lb) salmon fillet that I bought from Costco. I too am new to smoking but I had fantastic results because of the posts in this forum and the wealth of knowledge that the other forum members have and their willingness to share. For what it's worth, here's my advice:
-check out the archives and look for posts from a lady in Alaska named Andi...she's the Queen of smoked salmon and shares both her dry brine and wet brine recipes along with "how to". The other great source is Smokin Okie...check out his 101. On some of the threads the dialog between the two of them is REALLY informative! When I did my salmon I also did 5 whole rainbow trout. I viewed it as an experiment because I had not smoked fish before. Here's what I did:
-for the salmon I used Andi's dry brine recipe for 6 hours & for the trout I used her wet brine recipe for 4 hours.
-After dry brining the salmon and rinsing it THOROUGHLY it took about 4 1/2 hrs for the pelicle to form (very important!). I brushed the salmon lightly with maple syrup half way through the drying process. Then it was simple...I put the fish in the smoker on two racks with the trout below the salmon, used 2 ounces of hickory and set the temp at 150 degrees. Smoked the salmon for 3 1/2 hours and the trout for 6 1/2 hours ( they were whole trout ). The end result?
PERFECT....hope this helps.
