Preheat the oven to 200 ... dish and bake for 10 minutes. Then open the foil and bake uncovered for 10–15 minutes, until the fish is cooked and the skin is nice and crispy.

Bake for an hour, until soft. Remove from the oven, unwrap and foil and set aside ... then spoon the horseradish cream on top. Layer the trout or salmon on top of this, followed by the salsa.
