I do not soak in water.Do you soak in water before smoking? You do only a two day dry cure?
What's your sugar % with 1.65% salt?
I calculate the proper amounts of salt, cure#1, and sugar for a dry brin and then just toss a whole 3-4 pound salmon fillet in a 2 gallon ziplock bag and add the salt, cure#1 and sugar all on and around it in the bag and massage it around to be fairly even. I then squeeze the air out and set in the garage fridge.
The number of days is based on how thick the salmon is plus a couple of days for safety. The salt and cure #1 travels at 1/4 inch every 24 hours so a 2 inch thick fillet I let it cure for like 6 days and then into the smoker for cold smoking.
When I'm done putting smoke on it I remove it from the smoker, slice it and vac seal the slices... the ones I don't eat then :D
As simple as that!
Oh I do add orange and lemon zest or the Real Orange and Real Lemon granulated citrus to the cure for that fresh citrus flavor but you don't have to add that.
