What is the difference between the colored tapioca pearls and the black/brownish tapioca pearls?
They are both made from tapioca starch. The colored tapioca pearls have pastel colors added to them to make it look more like candy. After cooking them and adding sugar, they have a cotton candy taste. The black/brownish tapioca pearls are the original pearls that were used in the original bubble tea drink. The black/brownish color comes from a bit of caramel added to the starch during preparation. After cooking the black/brown tapioca pearls and adding sugar, it has a sweet caramel taste.
