What is a grit obtained from some palm trees called?

Sago is a starch extracted from the spongy centre, or pith, of various tropical palm stems. It is a major staple food for the lowland peoples of New Guinea and the Moluccas, 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 Europe and North America 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 (papeda), or as a pancake.
