Why Tapioca In Bubble Tea

Tapioca is used in bubble tea for its distinctive texture , known in Asian food culture as 'Q', meaning springy and chewy. Derived from cassava root starch, tapioca pearls have a neutral flavour that readily absorbs the sweet brown sugar syrup they are soaked in. This creates a satisfying contrast to the smooth liquid of the milk tea. (Source: nlb.gov.sg)
