Tapioca pearl is also known as boba to some cultures. It is produced by passing the moist starch through a sieve under pressure. Tapioca pearl is a common ingredient in Asian desserts such as kolak, in tapioca pudding, and in sweet drinks such as bubble tea, fruit slush and taho, where they provide a chewy contrast to the sweetness and texture of the drink.
Small pearls are preferred for use in puddings; large pearls are preferred for use in drinks. These large pearls most often are brown, not white (and traditionally are used in black or green tea drinks), but are available in a wide variety of pastel colors.
Not only are they used in the aforementioned drinks, they are also available as an option in shave ice and hot drinks. In addition to their use in puddings and beverages, a recent innovation has seen tapioca pearls baked inside of cakes.
