Bubble tea
Bubble tea (also known as pearl milk tea, boba milk tea, boba juice or simply boba) (, also ) is a Taiwanese tea-based drink invented in Taichung in the 1980s. Most bubble tea recipes contain a tea base mixed/shaken with fruit or milk, to which chewy tapioca balls or fruit jellies are often added. Ice-blended versions are usually mixed with fruit or syrup, resulting in a slushy consistency. There are many varieties of the drink with a wide range of ingredients. The two most popular varieties are bubble milk tea with tapioca and bubble milk green tea with tapioca.
