I keep 2-4 per season and make smoked trout dip. Nothing fancy on the fish, just some salt and pepper, then 3 hours at 225 in the smoker. Pull the meat, don't worry too much about the bones.
For every 8oz of smoked trout
1/2 C cream cheese
1/2 C sour cream
Juice of one lemon
2 T prepared horseradish
Process in food processor until smooth, remove to sealable container
Fold in
2 T red onion, small dice
2 T fresh flat-leaf parsley, small dice
Give it at least 24 hours to let flavors meld. Serve with crackers, grapes, etc. Great with lettuce and tomato on a sandwich if you're a fan of smoked whitefish salad.
