Yield Makes 4 servings

Number Of Ingredients 10

3 tablespoons olive oil
1 large onion, halved lengthwise, then thinly sliced crosswise
3 tablespoons water
1/2 teaspoon black pepper
3 tablespoons unsalted butter
3 tablespoons capers (in brine), rinsed, drained, and coarsely chopped
2 1/2 tablespoons fresh lemon juice
4 (6-oz) pieces mahimahi fillet (1 1/2 to 2 inches thick) with skin
3/4 teaspoon salt
2 tablespoons chopped fresh flat-leaf parsley

Steps:

Heat 2 tablespoons oil in a 12-inch heavy skillet over moderately high heat until hot but not smoking, then sauté onion, stirring frequently, until golden, about 6 minutes. Stir in water and 1/4 teaspoon pepper and cook, stirring, until onion is softened, about 1 minute. Stir in butter until melted, then stir in capers and lemon juice. Remove from heat and keep warm, covered.
Preheat broiler.
Pat fish dry, then brush all over with remaining tablespoon oil and sprinkle with salt and remaining 1/4 teaspoon pepper. Put fillets, skin sides down, on rack of a broiler pan and broil about 5 inches from heat until just cooked through, 6 to 8 minutes.
Serve fish topped with onion mixture and sprinkled with parsley.
