Cataplana de Marisco is a seafood dish that is cooked in a traditional Portuguese copper pot called a cataplana. It is made with a variety of fresh seafood, such as shrimp, clams, mussels, and fish, cooked with onions, garlic, tomatoes, and white wine. The dish is then simmered in the cataplana, allowing the flavors to meld together and create a delicious and aromatic seafood stew. Cataplana de Marisco is often served with crusty bread to soak up the flavorful broth.
