Large Asian pearl tapioca is used in desserts, like old-fashioned tapioca pudding and in Taiwanese bubble, or boba, tea. Cooking methods vary, but cooking completely is essential to achieve a desirable texture, rather than a starchy and unappealing dish. Well-cooked, the tapioca pearls should have a slightly chewy texture, similar to gummy-style candy, but they have very little natural flavor. Tapioca pearls are available in their natural white or a variety of colors, some with a slight flavor added.
Bring 8 cups of water to a full, rolling boil over high heat.
Pour 1 cup of tapioca pearls into the boiling water. Pour slowly and stir as you go to keep the balls from sticking together. Continue stirring for one minute.
Reduce the heat to medium and cover.
Cook the tapioca pearls for 15 minutes. Turn off the heat, but leave the pot covered for an additional 15 minutes.
Rinse well with cool water and drain. If you're planning to use the pearl tapioca for bubble tea, cover in sugar syrup or brown sugar and use immediately.
