Hearty fillets are needed for this casserole-cooked dish, otherwise the fillets may fall apart. In the Basque region of Spain, where this dish originates, hake (merluza) is used; it's a long, gray-skinned fish, rather cod-like in appearance. It is the most widely used fish in Spain, but you may substitute cod, or other thick, meaty fillets. In the Basque region, the dish is often served at table right out of its casserole; in fancier restaurants, a decorative arrangement of the ingredients is made on each plate. We prefer the latter method, because the white fillets, green vegetables, yellow egg yolks, and black mussels look so strikingly Spanish together on a white plate. Serves 4
