where do the bubbles in bubble tea come from
Tapioca balls Tapioca balls are a product that comes from tapioca, a starch which is in turn extracted from the cassava root.[1] They are also known as boba (a transliteration of the word “bubble”) or “pearls” in bubble tea. Some boba are five-to-ten-millimeter starch balls, consisting of sweet potato powder, potato powder, or jelly. By adding different ingredients—water, sugar and seasoning—tapioca balls can be made to vary in color and in texture. Tapioca balls are typically neutral in flavor and gel easily, making it often used as a thickening agent in foods like pudding.[2]
