The ideal fish for this Norman preparation is Dover sole—the real thing, a fish with great flavor and unmatched texture. But this isn’t an ideal world—you’re unlikely to find Dover sole and equally unlikely to want to pay the asking price if you do. Fortunately, cod is a good substitute. In fact, as long as you don’t overcook it, it’s fantastic here. Any firm but not tough white fillet will also work: red snapper and black sea bass are excellent choices. If you can pick up mussels at the same time, by all means go for the variation; the broth and overall results will be improved markedly. In Normandy, this would inevitably be accompanied by a potato gratin like the one on page 482 and, if you were lucky, a salad.

　　

Ingredients

makes 4 servings

　　2 tablespoons butter

　　1 large onion, sliced

　　Salt and black pepper to taste

　　1 1/2 to 2 pounds fillets of cod or red snapper, about 1 inch thick, in 1 or 2 pieces

　　2 cups dry sparkling cider

　　Chopped fresh parsley leaves for garnish

　　

Step 1

Preheat the oven to 400°F. Put the butter in a small skillet and turn the heat to medium. Add the onion and a sprinkling of salt and pepper and cook, stirring occasionally, until the onion is soft but not yet beginning to brown. Turn off the heat. Transfer the onion to a flameproof ceramic or nonstick baking dish just large enough to contain the fish. Sprinkle the fish with salt and pepper and put it over the onion. Pour the cider around all and bring to a boil on top of the stove.

　　

Step 2

Cover with foil and bake for 12 to 15 minutes, or until the fish is done (a thin-bladed knife inserted into its center will meet little resistance). Garnish with parsley and serve the fish with the onion and juices spooned over it.

　　

Cod Poached in Cider with Mussels

Step 3

Clean 2 pounds mussels (page 208) and combine them with the cider in a covered pot. Turn the heat to high and cook, shaking the pan occasionally, until the mussels open, about 10 minutes. When they are cool enough to handle, remove them from their shells; pass the cider through a cheesecloth-lined strainer. Proceed as directed, using the mussel-scented cider for the liquid and adding the shelled mussels to the fish about halfway through its cooking time.

　　

Cod Poached in Cider with Mushrooms

Step 4

In step 1, when the onion begins to soften, add 1 cup trimmed and chopped white, cremini, or portobello mushrooms and continue to cook, stirring occasionally, until the mushrooms have given up their liquid, about 10 minutes more. Proceed as directed.
