Optional – Add 3 pads of butter & a couple of lemon slices to the body cavity & another couple of slices of lemon on top. If you prefer, you can skip this step. A simple, plain smoked trout is delicious!
Smoke it until the temperature of the fish reaches 160 degrees. This took about 2-3.5 hrs, but the amount of time will vary significantly, so keep checking the temperature.
