Merluza en salsa verde
Bilbao families have cooked merluza en salsa verde in a shallow clay cazuela for generations, and it still turns up at Sunday lunch and on Christmas Eve. The sauce is just olive oil, garlic, parsley and the fish's own juices, thickened by gently shaking the dish so the gelatine from the hake binds it, much like a pil-pil. Clams open on top at the end. A common mistake is stirring with a spoon, which breaks the fish; swirl the dish instead. Chef's tip: keep the heat low once the hake goes in, because the sauce only comes together when it barely simmers.
