Spain is one of the most prolific mussel-producing countries in the world. The "raft" method is used in the Galician estuaries, where wooden platforms are chained to the bed and the mollusks are bred on ropes. The shells are large and black, and their meat is orange. Mussels can be preserved naturally (in their own juice), pickled (in a vinegar, white wine, and paprika sauce), or fried.
