First the Brine. i have been using Smokehouse brand brine, and pretty much follow the directions. Soak fillets overnight in the brine in the fridge.

It says to pat them dry after removing from brine, but i usually don't do that. An old time smoker said i should rinse the slime off in cold water them if possible let them sun-dry. So thats what i do. After they are dry i usually rub on some crushed red pepper (i have found this to be the best for my taste) or i may experiment with a fillet or two of some other spices.
now its time for the smoker. this is my set-up. I know it looks rough, but it was virtually free. It is an old CAST IRON wood stove with an external Weber Smokey Joe for a heat source. the cast iron heats up evenly and seems to maintain temps better.

I start the heat with Kingsford mesquite flavored charcol. once that gets going and my temp hits about 125-140 i will throw in a rack or two of fillets. i let them warm up for an hour or so then throw on some Smokehouse mesquite chips on the coals. I will let it smoke real good for a couple few hours trying to keep it around 125-150. (with an external wood heat source it can be a little difficult to keep the temp real constant.
finally after the smoke dies out (about 4 hours in) i check them tasty trout fillets. Depending on the size, i will cook up to a total of 5-10 hours. let them cool, vacuum seal those babies, and your good to go. I have also tried apple and hickory, but mesquite has worked the best for me.
Well, there you have it. It would be great to hear some advice on my method, and possibly some tips or your recipes. If you haven't already, get those smokers fired up!!
