Serve with Garlic Mashed Potatoes. You don't know where the fish ends and the potatoes begin in this beautiful and satisfying dish Chef Desmond, of Island Cottage on Hare Island in Ireland, uses turbot that comes from the waters off nearby Clear Island. We call for halibut, which is more readily available here.
1/4 cup finely chopped shallots
1/4 cup white wine vinegar
1/4 cup dry white wine
1/2 cup whipping cream
3 tablespoons vegetable oil
12 ounces mushrooms, chopped
1/2 teaspoon dried crushed red pepper
2 medium zucchini, trimmed, cut into matchstick-size strips
4 8-ounces halibut fillets (about 1 inch thick)
1/2 cup (1 stick) chilled butter, cut into pieces
2 medium tomatoes, peeled, seeded, chopped (about 1 cup)
2 tablespoons chopped fresh sorrel or spinach
Combine shallots and vinegar in heavy small saucepan. Boil until most of liquid evaporates, about 4 minutes. Add wine; boil until most of liquid evaporates, about 3 minutes. Whisk in cream. Set sauce aside.
Preheat oven to 400°F. Heat 2 tablespoons oil in heavy large skillet over medium-high heat. Add mushrooms and crushed red pepper. Cook until mushrooms are deep golden brown, stirring frequently, about 12 minutes. Add zucchini and sauté 2 minutes. Season to taste with salt and pepper.
Meanwhile, lightly oil baking sheet. Place halibut on sheet and brush with remaining 1 tablespoon oil. Bake until fish is opaque in center, about 10 minutes.
Bring sauce to simmer. Reduce heat; add butter and whisk just until melted. Remove from heat. Mix in tomatoes and sorrel. Season with salt and pepper.
Spoon Garlic Mashed Potatoes onto center of 4 plates. Place halibut atop potatoes. Arrange mushroom mixture around potatoes. Spoon sauce over fish and serve.
