Depending on what you want to do with the end product, here's a really simple recipe that works:
Thaw a fair sized salmon filet.
Put on CS rack skin side down.
If getting fancy, season with pepper and/or dill.
Smoke at 175F with about 2oz birch or alder until salmon is flaky, about 1 hour.
Remove from smoker and put in stomach.
Another simple recipe is the one in the CS booklet, something like 1/2 cup each of TenderQuick and brown sugar in a quart of water, marinate salmon for a few hours.
