Baked Wild Salmon with Herb Butter

Just about any type of fish can be baked, whether whole, cut into steaks, or filleted. Season the fish with salt and place it in an oiled baking dish or on an oiled rimmed baking sheet; the fish may give off some liquid as it bakes so it is best to use something with sides. Bake fillets and steaks in a hot oven, about 425°F. Whole fish, which will take longer to cook, should bake in a 375°F oven. Most fillets are done when they are just cooked through at the center, the flesh opaque but still moist. Some exceptions are tuna, albacore, and salmon, which are much tastier when cooked medium rare with the flesh still translucent in the center. When cooked on the bone, whole or in steaks, all types of fish need to be cooked until the flesh can be lift ed from the bones, but just to this point and no longer. It is important to not overcook fish or it will become dry and tough. Fillets cook fairly quickly: depending on the thickness, they take from 7 to 10 minutes. A good gauge for cooking whole fish is 10 minutes per inch of thickness measured at the thickest part of the fish. Whole fish can be slashed diagonally to the bone to speed up the cooking. These are only rough guides and you should check the fish oft en while it is cooking to judge its doneness. Gauge the doneness by pushing in the flesh with your finger. It will feel soft when underdone; as it cooks and sets it will begin to feel a bit springy. Don’t hesitate to cut into it to know for sure. Besides a basic seasoning of salt, you can add a splash of wine and a drizzle of extra-virgin olive oil or a pat of butter for more flavor and moisture. The fish also can be infused with a marinade before baking; marinades can be made from herbs, spices, citrus zest and juice, and olive oil. Fillets and steaks can be painted or smeared with Pesto (page 230), Chermoula (page 233), or other flavorful sauces before they are slipped into the oven. Wrap whole fish or fillets in aromatic fig or grape leaves or in branches of lime, lemon, or fennel so the leaves can perfume the fish and help trap moisture. Fish can also be baked in a juicy sauce such as a tomato sauce, seasoned sautéed onions, or a vegetable ragout. Add 5 minutes or so to the cooking time when baking fish in sauce. Salmon fillets have easy-to-spot pin bones—a row of thin white rib-like bones that extends from behind the gills to the fish’s midsection. Rub your fingers over the flesh to locate these bones; use a pair of needle-nosed pliers to pull them out of the flesh.
