The salt creates a seal around the fish, which preserves its moisture and pure flavors. Romesco is a classic sauce from the Catalonia region. For cooking the fish, use two 13x9x2-inch metal baking pans.
Chef José Andrés says that comparing pimentón, a Spanish smoked paprika, to the supermarket variety is like "comparing it to red powder." Pimentón is the sweetly smoky flavor in everything from chorizo sausage to paella. Look for dulce (sweet) and de la Vera on the label. Peppers from the La Vera region are always smoke-dried; in other regions they are sun-dried.

Preparation
For sauce:
Step 1
Preheat oven to 400°F. Toss tomatoes, bell peppers, and onion in small baking dish with 2 tablespoons olive oil. Roast until partially charred, turning every 15 minutes, about 45 minutes. Cover with foil; let stand 15 minutes.
Step 2
Meanwhile, heat 1 tablespoon olive oil in small skillet over medium-high heat. Add chile; fry until darkened and slightly puffed, turning once, about 30 seconds. Transfer to small bowl. Add enough hot water to cover. Let stand 30 minutes.
Step 3
Peel and seed ancho chile, tomatoes, and bell peppers; place in blender. Peel onion; coarsely chop and add to blender.
Step 4
Heat 1 tablespoon olive oil in small skillet over medium-high heat. Add almonds; sauté until lightly toasted, about 1 minute. Transfer to blender. Add 1/4 cup extra-virgin olive oil, garlic, vinegar, bread, and paprika to blender; blend to coarse puree. Transfer to bowl; season with salt. (Can be made 1 day ahead. Cover and chill. Bring to room temperature before serving.)
For fish:
Step 5
Preheat oven to 450°F. Place 1 fish in each of two 13x9x2-inch metal baking pans. Cover each fish with 3 pounds salt. Drizzle 1 1/2 cups water over salt in each pan. Using hands, pack salt over fish to cover completely.
