Boba milk tea, also known as pearl milk tea or PMT, is a Taiwanese tea-based drink invented in tea shops in Taichung, Taiwan, during the 1980s. Most bubble tea recipes contain a tea base mixed with fruit or milk. Ice-blended versions are usually mixed with fruit or syrup, resulting in a slushy consistency. Most bubble teas come with small chewy tapioca balls, commonly called ?pearls? or ?boba? .
There are many variants of the drinks, and many kinds of types are used and ingredients added. The most popular bubble drinks are bubble milk tea with tapioca and bubble milk green tea with tapioca.
