From humble beginnings of making white or black tapioca pearls (hereinafter referred to as just pearls) out of cassava flour, now, there are pearls in all sorts of colors or popping boba (also called magic beans or fruit balls), plus matching ingredients like pudding, grass jelly, fruit, etc. with seasoning, syrup, and tea leaves to create endless combinations. It can be said that this is the principal reason for the bubble tea industry's gradual development from Taiwan to Hong Kong, Mainland China, Southeast Asia, Japan, Korea, North America, Europe, and even Latin America, Africa, and the Middle East.
