This shelf-stable seafood master stock has been made with love and care. 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.
