Tapioca pearls should be stored in an airtight container in a cool, dry place. Avoid exposing the pearls to direct sunlight or high temperatures, as this can cause them to spoil or lose their texture and flavor. If stored properly, tapioca pearls can last for several months.
It is also important to keep the pearls dry and free from moisture, as moisture can cause the pearls to become sticky and difficult to use. If you have opened the package and there is any moisture present, simply spread the pearls out on a dry, clean surface and allow them to air-dry before returning them to their storage container.
