Popping boba

Popping boba, also known as Popping pearls, is a topping used in bubble tea. Unlike traditional tapioca pearls (which are made of tapioca), Popping boba consists of a gel-like skin with juice of any flavor on the inside. This requires a spherification process.
Popping boba is also used as a topping in smoothies, slushies, and frozen yogurt.
