Paksiw (Tagalog: [ˈpak.sɪʊ]) is a Filipino style of cooking, whose name means "to cook and simmer in vinegar". Common dishes bearing the term, however, can vary substantially depending on what is being cooked. Pinangat na isda may sometimes also be referred to as paksiw, though it is a different but related dish that uses sour fruits like calamansi, kamias (bilimbi) or sampalok (tamarind) to sour the broth rather than vinegar.
