My friend Carlos Lorenzo has a great little article about one of the most delicious anchovies you will ever taste. They are well known in Cataluña: Anchoas de L'Escala. L'Escala by the way, is a gorgeous little town north of Barcelona, close to the French border and is definitely worth a visit. But if you can't visit, just eating its anchovies will be heaven on earth.
