Tapioca pearls are made from a starch extracted from the cassava root (Tapioca) that's processed to make the chewy pearls commonly used in Bubble tea. They are made by pushing moist tapioca starch through a sieve. The pearls are a naturally gluten-free thickening agent. Used in traditional Filipino Coconut and Mango pudding they also add an interesting texture in popsicles. Large pearl size in diameter: 6mm - 9mm
