Sago is a starchy, fecula, a granular substance used in cooking. It is very similar to tapioca and is used for much the same purpose.
Sago is the pith found inside the stems of some cycad plants of the genus Cycas, the most notable being Cycas revoluta. The pith is ground to a coarse flour, washed carefully to leach out natural toxins, and the portion that is removed during washing is dried and cooked. It is eaten in the lowlands of Irian Jaya and on the Moluccas.
Sago can be made into steamed puddings, such as sago plum pudding , or ground into a powder and used as a thickener for other dishes or as a dense glutinous flour.
The Sago Cycad or "Sago Palm" is a slow-growing ornamental plant.
