What Is Boba Made Of?

Boba tea first became popular in Taiwan in the 1980s. Properly cooked boba pearls are soft and chewy. Sweet potato or another starch is often added to the black boba pearls, as is some amount of sugar. White boba pearls often use chamomile root and caramel instead. Boba are usually served in black or green tea, often with milk and various fruit flavors mixed in.
