Bubble tea, also known as boba tea, originated in Taiwan in the 1980s. It is a sweet, tea-based drink that typically combines black tea, green tea, or oolong tea with milk or fruit flavors. The drink is famous for its chewy tapioca pearls, often referred to as "boba," which sit at the bottom of the cup. The preparation of bubble tea involves shaking the tea with ice and sweeteners, then adding the tapioca pearls. It is usually served in a clear cup with a wide straw, allowing drinkers to enjoy both the liquid and the chewy pearls. Variations include different flavors, toppings, and types of tea.
