Taiwan's most famous drink and its best-known culinary export — sweetened milk tea poured over a bed of chewy black tapioca pearls, sipped through a fat straw so the pearls come up with the tea. The pearls are cooked from tapioca starch until springy, soaked in brown-sugar syrup, then dropped into iced or hot tea shaken with milk. From 1980s Taichung tea houses it spread across the world as 'boba'.
Bubble milk tea emerged in 1980s Taichung, and two tea houses claim its invention. Chunshuitang says its product manager Lin Hsiu-hui dropped sweetened tapioca pearls into iced milk tea around 1985-86 and the shop named the drink in 1987. Hanlin Tea House in Tainan says its founder Tu Tsung-ho, after opening in 1986, was inspired by white tapioca pearls sold at the Yamuliao market and stirred them into milk tea. The two sides sued each other for about a decade; the court ultimately ruled bubble milk tea a new kind of beverage rather than a patentable invention, so anyone may make it — which is exactly why it spread everywhere.
A fat straw brings up tea and pearls together. The tea is cold, milky and sweet; the pearls are warm-cool, glossy black, and bounce against the teeth — a soft, springy resistance before they give way, faintly chewy at the core with the dark-caramel taste of brown sugar. The pleasure is the contrast of liquid and texture in one mouthful, swallow after swallow.
The pearls' chew is pure starch science. Tapioca starch is dough-kneaded with near-boiling water so its granules gelatinise into a cohesive paste, rolled into balls, then boiled: outside the granules swell and burst into a soft skin while the centre stays denser, giving the signature springy-then-yielding bite. Because cooked tapioca starch retrogrades and hardens within hours, the pearls must be eaten the day they are boiled — left overnight they turn stiff and cloudy. A soak in brown-sugar syrup keeps them slick, sweet and dark.
Variations
Endless: swap black tea for green, oolong or roasted tea; milk for fresh dairy, evaporated milk or non-dairy creamer; pearls for the larger 'boba' or grass jelly, pudding and taro balls. Reduced-sugar and reduced-ice are standard order options. The Hong Kong-style version uses strong evaporated-milk tea; many global chains over-sweeten.

Drain the pearls, rinse briefly, and soak them in warm brown-sugar syrup.
Watch outServe the pearls the same day they're boiled — cooked tapioca hardens and clouds within hours; overnight they go stiff.
