Beef papaitan is a traditional Filipino soup from the Ilocos region, made with beef innards like tripe, liver, and intestines. Its name comes from “pait” meaning “bitter,” because the broth is flavored with bile - a unique ingredient that gives the dish its signature taste. Think of it as the Filipino cousin of other “nose-to-tail” dishes worldwide, where every part of the animal is used to create deep, rustic flavors.
