Aneto roasts the fish bones (including angler fish, codfish, conger and scorpion fish) and then sautes market fresh vegetables to make a sofrito the traditional way before simmering for 2 hours. This is obviously incredible as the stock element for seafood paella, but it also makes for a life-changing seafood stew. Use with caution - because once you try this, you won't ever look back. Contains shellfish.
