Popping boba

Popping boba is a type of "boba" used in bubble tea. Unlike traditional boba, which is tapioca-based, popping boba is made using the spherification process that relies on the reaction of sodium alginate and either calcium chloride or calcium lactate. Popping boba has a thin, gel-like skin with juice inside that bursts when squeezed. The ingredients for popping boba generally consist of water, sugar, fruit juice or other flavors, and the ingredients required for spherification.[1]

In addition to being used in place of traditional boba in bubble tea, it is used as a topping for frozen yogurt.
