Popping boba, also known as popping pearls or bursting boba, are small, gel-like balls filled with fruit-flavored juice. When bitten or squeezed, the thin outer layer bursts, releasing a refreshing burst of liquid. The outer layer is usually made of a natural substance like seaweed extract, formed through a process called “spherification,” which creates the round shape and juicy center. Popping boba is popular in bubble tea, frozen yogurt, and dessert toppings because of its satisfying “pop” and sweet, fruity taste. Common flavors include mango, strawberry, lychee, and passion fruit.
