Paella is internationally renowned Spanish rice dish. It originated in the Spanish province of Valencia. The dish can be made with a large variety of ingredients, from different sea food, to meat to vegetables. Probably the most well-known is the seafood version, with the decorative looking large shrimp and mussels in shells. The necessary basis for the dish is formed by rice which should be a medium-grain variety which can absorb a lot of liquid. The yellow color of rice is typically obtained by using saffron. Paella should be prepared on a large, flat steel pan called paellera.
