Sago seeds are small, starchy granules derived from the pith of the sago palm (Metroxylon sagu), native to Southeast Asia. Often referred to as “sago pearls,” they are processed into spherical form and used as a carbohydrate-rich food ingredient. Commonly used in puddings, desserts, and fasting recipes, sago is valued for its easy digestibility and high energy content, though it offers minimal protein and fiber.
