You bury a whole sea bass in a crust of wet salt and bake it until the crust is hard as plaster. At the table you crack it open: the skin comes away, the flesh is steamed in its own juices, and there is almost no seasoning because the salt has done the quiet work of not entering the fish.
It is a coastal trick from Alicante to Catalonia — any whole white fish will do, orata or dorada if you haven't bass. The crust looks dramatic; the cooking is gentle. Lemon and oil at the table are the rest of the plate.
Don't salt the fish. The crust is enough. Rest five minutes, then crack. Albariño, or a dry Verdejo. Serve with a green salad and nothing clever.
Method
- 01
Heat the oven to 400°F. Pat the fish dry, inside and out. You do not salt it — the crust will season the skin and leave the flesh alone, which is the whole trick. Tuck the thyme and a few lemon slices into the cavity. Oil a tray lightly so the crust doesn't weld itself to the metal.
- 02
Stir the coarse salt with the egg whites until it feels like wet sand and holds when you squeeze it. Spread a bed of that salt on the tray, set the fish on it, and pack the rest over and around until the fish disappears, leaving only the tail if you like a handle. It should look like a white loaf. Don't leave gaps, or the steam will escape.
- 03
Bake until the crust is hard and faintly gold, 30 to 35 minutes for a fish this size. A skewer through the thickest part, if you must peek, should come out hot. Rest 5 minutes. Carry the whole thing to the table — the cracking is half the dinner.
- 04
Strike the crust with the back of a spoon and lift it away in pieces. Peel off the skin; the flesh should be just opaque, moist, and barely saline. Lift it onto plates, moisten with oil and a squeeze of lemon. Discard the salt crust; it has done its work. A green salad, bread, and a glass of Albariño. Nothing else.
