Sago /ˈseɪɡoʊ/ is a starch that comes from the spongy centre of tropical palm stems. In many cases, it comes from Metroxylon sagu. It is a major staple food for many people living in New Guinea and the Moluccas. It is called saksak, rabia, and sagu in those areas.
The largest suppliers are usually in Southeast Asia, particularly Indonesia and Malaysia. Big quantities of sago are often sent to Europe and North America for cooking purposes.
