What is crystal boba?

Crystal boba, also known as popping boba, bursting boba, or popping pearls, is a chewy, translucent sphere filled with a liquid center that bursts in your mouth when bitten. Here's what distinguishes it:

• Texture: The outer shell is made from a seaweed-based ingredient (usually sodium alginate) and has a unique, slightly chewy texture. This contrasts with the typical tapioca pearls used in traditional boba tea.

• Flavor: The liquid inside is typically a fruit juice or a flavored syrup, providing a burst of flavor when the boba pops. Popular flavors include mango, lychee, strawberry, passion fruit, and even more unusual options.

• Appearance: Crystal boba is usually clear or slightly colored, depending on the flavor of the filling. This translucent nature contributes to its unique visual appeal.

• Production: The creation involves a process called spherification, where a flavored liquid is dropped into a sodium alginate bath, creating a thin, gel-like shell around the liquid center.

• Health Considerations: While generally considered safe, some people might experience allergic reactions to sodium alginate (though it's relatively rare). The sugar content of the filling can also be a concern, so it's important to be mindful of portion sizes, especially if watching sugar intake.

Crystal boba is a popular addition to many tea drinks, smoothies, and even yogurt bowls, adding both texture and flavor complexity. Its unique mouthfeel makes it a fun and refreshing addition to many beverages.
