Also, if you have skinless, boneless filets, dusting them lightly in brown sugar and french onion soup mix is great! Fry them in a suitable high-heat oil, but keep them on low at first so the sugar doesn't caramelize and burn!
If you have a good salmon or good tasting trout, get a pan, preferably cast iron, and poach skinless/boneless filets in a mixture of honey and white wine. I don't flip the pieces...just maybe cover them partially with tinfoil so the top cooks a bit...it often takes 25 minutes, but is great!
Take the fish out a bit early and put it on a hot plate to finish cooking. Crank the heat and reduce the honey/wine until it is of suitable consistency, and pour over the fish!
Also, a light coating of mayo mixed with lemon juice, lots of fresh dill, salt and pepper is great.
Another favorite is marinading trout in a smoking brine - 5 parts brown sugar, 1 part coarse salt - and pulling them out early. 4 or 5 hours is great, then fry the fillets in hot oil in a pan. This is excellent!
Kokanee is great that way. Fry it skin-side down on low-med heat so the skin gets crispy. Wait until it is mostly cooked skin side down, then flip it and fry the top briefly on high heat.
