Sago

Sago is a <a href="/facts/Starch/gHAqGfJb">starch</a> extracted from the <a href="/facts/Pith/luGP442D">pith</a>, or spongy core tissue, of various tropical palm stems, especially those of <a href="/facts/Metroxylon_sagu/tuQtP23Y">Metroxylon sagu</a>. It is a major <a href="/facts/Staple_food/GNo3putV">staple food</a> for the lowland peoples of <a href="/facts/New_Guinea/qB0bzfSH">New Guinea</a> and the <a href="/facts/Maluku_Islands/Bwucm34R">Maluku Islands</a>, where it is called saksak, rabia and sagu. The largest supply of sago comes from Southeast Asia, particularly Indonesia and Malaysia. Large quantities of sago are sent to <a href="/facts/Europe/DTAtrKfh">Europe</a> and <a href="/facts/North_America/djNjCQIl">North America</a> for cooking purposes. It is traditionally cooked and eaten in various forms, such as rolled into balls, mixed with boiling water to form a glue-like paste (<a href="/facts/Papeda_(food)/WMpe4TKK">papeda</a>), or as a <a href="/facts/Pancake/v9LJhSno">pancake</a>.
Sago is often produced commercially in the form of "pearls" (small rounded starch aggregates, partly <a href="/facts/Starch_gelatinization/8ACEzpyM">gelatinized</a> by heating). Sago pearls can be boiled with water or milk and sugar to make a sweet <a href="/facts/Sago_pudding/SvRMRQ0Q">sago pudding</a>. Sago pearls are similar in appearance to the pearled starches of other origin, e.g. <a href="/facts/Cassava/KvjKQDkV">cassava</a> starch (<a href="/facts/Tapioca/kKWBug24">tapioca</a>) and potato starch. They may be used interchangeably in some dishes, and tapioca pearls are often marketed as "sago", since they are much cheaper to produce. Compared to tapioca pearls, real sago pearls are off-white, uneven in size, brittle and cook very quickly.
The name sago is also sometimes used for starch extracted from other sources, especially the sago cycad, <a href="/facts/Cycas_revoluta/PSg7vmoX">Cycas revoluta</a>. The sago cycad is also commonly known as the sago palm, although this is a misnomer as <a href="/facts/Cycad/Kc2JDExr">cycads</a> are not <a href="/facts/Palm_(plant)/5bN6Wwcr">palms</a>. Extracting edible starch from the sago cycad requires special care due to the poisonous nature of cycads. Cycad sago is used for many of the same purposes as palm sago.
The <a href="/facts/Fruit/PBpuzk60">fruit</a> of palm trees from which the sago is produced is not allowed to ripen fully, as full ripening completes the life cycle of the tree and exhausts the starch reserves in the trunk to produce the seeds to the point of death, leaving a hollow shell. The palms are cut down when they are about 15 years old, just before or shortly after the <a href="/facts/Inflorescence/CvpNd4vS">inflorescence</a> appears. The stems, which grow 10 to 15 meters (35 to 50 feet) high, are split out. The starch-containing <a href="/facts/Pith/luGP442D">pith</a> is taken from the stems and ground to powder. The powder is kneaded in water over a cloth or <a href="/facts/Sieve/LJBztC9f">sieve</a> to release the starch. The water with the starch passes into a trough where the starch settles. After a few washings, the starch is ready to be used in cooking. A single palm yields about 360 kilograms (800 pounds) of dry starch.
