If you want to experiments with flavoring trout, try a brine. Brining trout recipes can differ, but you can mainly brine trout one of two ways. You either dry brine or wet brine it. When you dry brine, you will want to combine a mix of salt, sugar (brown) and pat onto the trout. Let it rest in the fridge for 6- 8 hours if you have the time. If you wet brine trout, you will include some sort of liquid like water in addition to the other ingredients.
