Cuttlefish sauce rice or another name in Spain called cuttlefish sauce paella, where seafood could be added.
Different types of seafood could be added according to one's taste. For example, shrimp, shellfish, crab, and so on. There was no seafood that couldn't be added. To put it bluntly, it was a Spain version of seafood stew.
As a matter of fact, having obtained a full set of Spain dishes, Yuan Zhou knew that nothing was added to the cuttlefish sauce rice in the beginning. Later on, it was improved in order to make a serving of rice more expensive.
The cuttlefish sauce rice cooked by Yuan Zhou was definitely the most traditional dish. It was a dish without any additional seafood, except for the cuttlefish sauce and some other seasonings. It wasn't that he was inflexible in thinking that the original dish was the best, but if other seafood was added to this dish, the original taste of the cuttlefish sauce would be ruined and it would become weird.
