jhud, morning.... Please stop into "roll call" and introduce yourself for a proper welcome from our members...
About the fish...... It needs to be brined or a dry rub put on it... Sit for a day or so in the refer, rinsed well, dried, and a pellicle formed to get the product you describe... Kippered Salmon is what that product is called....
I sprinkle salt/sugar.. 50/50 with a little garlic, onion and dill mixed in, add 1 level tsp cure #1 / 5#'s of fish... Wrap in plastic and refer for a couple days..... rinse well, dry and place in front of a fan on high for several hours until the pellicle is formed..... It should be dry to the touch and firm... smoke at 120 for a few hours then raise the temp to 200 until the IT of the fish is 135 ish deg... Smoke for the entire time....
You really didn't think fish that good was easy did you ???? Once you get the handle on making it, don't give any away.... You will be badgered to make some for others.... Your life will change forever.... You will have to sell your house and move....

Just a warning.... Dave
