How to Make It
In a shallow dish, season the fish with salt, black pepper and cayenne; spread in a single layer. Sprinkle the fish with 1 tablespoon of the cilantro. Cover with plastic wrap and refrigerate while you prepare the rest of the dish.
In a small bowl, cover the raisins with warm water and let stand until plump, about 10 minutes. Drain.
Meanwhile, in a large, deep skillet, combine the scallions and carrots with 4 cups of water and simmer the vegetables over moderate heat until the carrots are tender, about 10 minutes. Add the honey, preserved lemon peel, raisins and pine nuts, season with salt and black pepper and simmer the mixture for 10 minutes longer.
Slip the trout into the broth, cover and simmer over moderately low heat until the fish is just barely cooked through, about 10 minutes. Drizzle the fish with the olive oil, garnish with the remaining 2 tablespoons of chopped cilantro and serve.
Preserved lemons are cured in salt and lemon juice. They are available at specialty food markets and from chefshop.com.
