Tapioca pearls are small, round balls made from tapioca, a starch extracted from the cassava root. They are commonly used in various desserts and beverages, most notably in bubble tea, where they provide a chewy texture. The pearls are typically cooked in boiling water until they become soft and translucent. These pearls come in different sizes, ranging from tiny to large, and can be found in both white and black varieties. The black pearls are often colored with caramel or brown sugar, giving them a distinct flavor. Tapioca pearls are gluten-free and are enjoyed by many for their unique texture and versatility in recipes.
