Moronga, rellena, morcilla or mbusia is a kind of blood sausage. It is found in Argentina, Cuba, Colombia, Puerto Rico, Central America, Mexican and Paraguay cuisine. Spices, herbs (such as ruta, oregano, and mint), onions and chili peppers are added and then boiled in the pig's large intestines for casing for several hours. It is served in a sauce, either "chile rojo" or "chile verde". It is also served in central Mexico as a filling in gorditas and tacos after it has been pan-fried with fresh onions and jalapeño peppers. This sausage is called "morcilla" in the Yucatán Peninsula, and it is almost always served along with other sausages (buche) and a mix of pickled onion, cilantro, and spices.
