Arròs negre is a Spanish dish originating from Valencia and Catalonia, and it is the most popular in Castellon and Tarragona. It is made with white rice, squid or cuttlefish, and squid ink, which gives the dish its characteristical black color.
The dish is often enriched with the addition of garlic, onions, fish stock, cubanelle peppers, olive oil, and sweet paprika, and many cooks like to add other types of seafood into the paella pan, such as shrimp and crab.
