Sago is a type of food that is made from the starchy center of a plant called the sago palm. It is often used in desserts and puddings, especially in parts of Southeast Asia. To make sago, the starchy center of the palm tree is first harvested by cutting down the tree and removing the outer layers. Then it is processed into small, bead-like shapes that can be cooked in liquid until they become soft and translucent. Sago beads don't have much flavor on their own, so they are usually sweetened and flavored with things like sugar, coconut milk, or vanilla. When you eat sago, it feels kind of slippery and soft in your mouth, almost like a jelly. It is a popular dessert in many cultures and can be eaten hot or cold.
