This product developed in a sidelong manner from tapioca. It became apparent that if the manner of producing tapioca was modified to make it come out in regular round ‘pearls’, the product had more attraction. So tapioca in pearl form competed with regular tapioca, both being made from cassava starch, as tapioca still is. Then, towards the end of the 19th century, the pearls began to be made from the native product, potato starch, instead of the imported cassava starch. Thus the two products parted company.
