what are bubbles in bubble tea

The bubbles in bubble tea are small, round balls that are made from tapioca flour. These bubbles are also known as tapioca pearls or boba. Originally, the name "bubble tea" came from the foam bubbles that were created in the process of shaking to mix all the ingredients including tea, syrup, and powder to get the delicious bubble tea. Nowadays, most people refer to the bubbles in bubble tea as tapioca pearls or boba. The bubbles are an essential part of the bubble tea, and their softness and chewiness are what make bubble tea unique. The bubbles can be flavored with fruit juice, and some bubbles, called popping bubbles or popping bobas, are small balls filled with fruit juice that "pop" when bitten into. The bubbles are gluten-free, vegetarian, and easy to chew, making them a tasty option for those who are on a gluten-free diet.
