This particular sausage is made from a recipe typical of Asturias. It is made in the US by a native-born Spaniard. All the seasonings are imported from Spain. Onions and Spanish paprika/pimenton add a distinct flavor.
Morcilla black (blood) sausage with onion is popular throughout Spain. It is fundamental to Spanish cuisine -- used especially in stews or cocidos, but it is an equally tasty appetizer -- either grilled and served with a mixed salad, or sliced and fried as an accompaniment to eggs. You will receive 4 links per package -- each about 1 inch thick.
You may store morcilla in the refrigerator for up to a week, or in the freezer for up to 60 days. Cook to an internal temperature of at least 160 degrees Fahrenheit.
