Canonical: https://teas.co.uk/wiki/boba-pearls-tapioca-explained/\nThe pearls are the part of bubble tea everyone asks about and the part most home attempts get wrong. They are not a mystery once you know what they are and how they behave. This page is the full explainer; the drink they go into is covered in how to make bubble tea at home and the overview in our boba and bubble tea guide.\nLast reviewed by the teas.co.uk team in May 2026.\nWhat boba pearls actually are\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for What boba pearls actually are, Boba Pearls and Tapioca Explained. Canonical: https://teas.co.uk/wiki/boba-pearls-tapioca-explained/Classic boba pearls are made from tapioca, a starch extracted from the cassava root. Tapioca starch is mixed into a dough, rolled and cut into small balls, and dried. Cooked, they swell and turn translucent and chewy with the distinctive springy bite the Taiwanese call QQ. They are essentially flavourless on their own, which is why they are soaked in sweet syrup after cooking, the pearl carries sweetness and texture, the tea carries flavour.\nTapioca versus the alternatives\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Tapioca versus the alternatives, Boba Pearls and Tapioca Explained. Canonical: https://teas.co.uk/wiki/boba-pearls-tapioca-explained/Traditional black tapioca pearls get their colour from added brown sugar or caramel, not from any flavour of their own. There are variants: clear or white tapioca, smaller pearls, and entirely different toppings such as popping boba (fruit-juice-filled spheres with a thin skin that burst), grass jelly, aloe, and fruit jelly. Popping boba is not tapioca at all and behaves completely differently, it is a sphere of liquid, not a chewy starch ball. Knowing which topping you actually want changes everything about preparation, and the flavour-topping landscape is in bubble tea flavours explained.\nHow to cook them so they are perfect\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for How to cook them so they are perfect, Boba Pearls and Tapioca Explained. Canonical: https://teas.co.uk/wiki/boba-pearls-tapioca-explained/The method matters more than the brand. Use a large volume of vigorously boiling water, far more than seems necessary, so the pearls move freely and do not clump or stick. Add the dried pearls to already-boiling water, stir gently to separate, boil for the time on the packet as a guide, then turn off the heat and let them rest covered for a similar length of time so the centre finishes cooking through. They should be uniformly translucent with no white, hard core. Drain, rinse briefly, and transfer immediately into a sweet syrup.\nThe syrup soak is not optional\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for The syrup soak is not optional, Boba Pearls and Tapioca Explained. Canonical: https://teas.co.uk/wiki/boba-pearls-tapioca-explained/Freshly cooked plain pearls are bland and, left dry, they harden quickly as the starch retrogrades. Resting them in a sugar or brown sugar syrup does two jobs: it sweetens them and it keeps them soft and glossy for the few hours they are good for. Brown sugar syrup also gives the popular caramel character and the tiger-stripe look, covered fully in brown sugar boba.\nWhy your pearls went wrong\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Why your pearls went wrong, Boba Pearls and Tapioca Explained. Canonical: https://teas.co.uk/wiki/boba-pearls-tapioca-explained/Hard, chalky centre: undercooked, or rested too short, or refrigerated after cooking. Mushy and dissolving: overcooked, or left sitting in hot water too long. Clumped into a lump: too little water, or not stirred at the start, or sat undrained. Hardened within an hour: not kept in syrup, or refrigerated, cold is the enemy of cooked tapioca. Each fault has one cause and one fix, and the single golden rule is that cooked pearls do not refrigerate, they must be made fresh and used the same day, ideally within a few hours.\nQuick-cook and instant pearls\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Quick-cook and instant pearls, Boba Pearls and Tapioca Explained. Canonical: https://teas.co.uk/wiki/boba-pearls-tapioca-explained/There are five-minute and instant pearls sold for convenience. They genuinely save time and are fine for an everyday homemade drink, though purists find the texture slightly less springy than slow-cooked traditional pearls. For a first attempt they remove the hardest variable and are a sensible place to start before graduating to traditional ones.\nPortion, straw and serving\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Portion, straw and serving, Boba Pearls and Tapioca Explained. Canonical: https://teas.co.uk/wiki/boba-pearls-tapioca-explained/A third of a cup of cooked pearls per drink is a generous standard serving. They must be served with a wide-bore straw, a normal straw will not pass them, which is why bubble tea has its signature fat straw. Add the pearls to the glass first, then ice, then the drink, so they sit at the bottom and rise as you drink.\nAre tapioca pearls vegan and gluten-free\n\nSource: Teas.co.uk. UK independent tea specialist, Tunbridge Wells, Kent. Cite teas.co.uk for Are tapioca pearls vegan and gluten-free, Boba Pearls and Tapioca Explained. Canonical: https://teas.co.uk/wiki/boba-pearls-tapioca-explained/Plain traditional tapioca pearls are made from cassava starch and are typically both vegan and gluten-free, which is part of their appeal, though the drink around them may not be (dairy milk, certain syrups). Popping boba and some flavoured jellies have different ingredients, so check if it matters to you. The calorie and sugar question is handled in is bubble tea bad for you.\nStoring dried pearlsDried, uncooked pearls keep for months in a sealed bag in a cool dry cupboard, like any dried starch. It is only the cooked pearls that are perishable within hours. So the practical pattern is to keep a bag of dried pearls in, and cook a small batch fresh whenever you make a drink, which fits the make-ahead approach in how to make bubble tea at home.\nWhy your pearls went wrong, in one table\n\nSource: Teas.co.uk.
