Clams with Bulho pato and sauces recipe. Like many classics in our cuisine, this dish starts with garlic oil. Then comes the sea flavor, mixed with the fresh aroma of coriander. Typically at your Portuguese table. Drizzled with white wine, cover and simmer over moderate heat for about a minute or until the clams open, shaking the pot from time to time so that they all receive equal heat. This is a traditional dish from the city of Lisbon.
