Bubble tea
Bubble tea is a tea-based drink that originated in Taiwan in the early 1980s. Taiwanese immigrants brought it to the United States in the 1990s, initially in California through regions including Los Angeles County, but the drink has also spread to other countries where there is a large East Asian diaspora population. Bubble tea most commonly consists of tea accompanied by chewy tapioca balls ("boba" or "pearls"), but it can be made with other toppings as well, such as grass jelly, aloe vera, red bean, and popping boba. It has many varieties and flavors, but the two most popular varieties are pearl black milk tea and pearl green milk tea ("pearl" for the tapioca balls at the bottom).
