Taiwanese Bubble Tea

Taiwan's world-changing invention: cold black milk tea in a shaker with ice and sweet tapioca pearls that have been cooked to tender ebony spheres, served in a tall cup with a fat straw for the pearls to travel through

Origin: Taichung, Taiwan

From the journey of Tea.

Bubble tea (珍珠奶茶, zhēnzhū nǎi chá, 'pearl milk tea'; also called boba milk tea) was invented in 1986 at Chun Shui Tang tea house in Taichung, Taiwan, by Lin Hsiu Hui, a product development manager who added a scoop of cold fen yuan (tapioca pudding pearls) from her lunch to her iced milk tea during a staff meeting. The drink was an immediate sensation within the tea house, appeared on the menu the following week, and within two years had spawned hundreds of imitators across Taiwan. The invention was partly accidental and entirely Taiwanese: it combined the milk tea tradition of the British colonial era, received through Hong Kong and Cantonese culture; the tapioca pearl tradition of Taiwanese and Fujian sweet soups; the ice-shaking method of Taiwanese iced tea; and the thick straw necessary to accommodate the pearls, which became one of the most iconic objects in late-twentieth-century beverage culture. The 'bubble' in bubble tea originally referred not to the tapioca pearls but to the foam produced by shaking the tea with ice in a cocktail shaker: an earlier Taiwanese iced tea technique. Both bubbles are now present in the canonical preparation. From Taiwan, bubble tea spread to Hong Kong, Singapore, mainland China, and then globally, accelerating through diaspora networks in the 1990s and 2000s. By 2023, the global bubble tea market was valued at over 2.5 billion US dollars, with dedicated shops in virtually every major city in the world. The original pearl milk tea has spawned thousands of variants: fruit teas, matcha bases, cheese foam toppings, brown sugar boba, and taro milk tea are among the most popular. This recipe describes the original classic: black milk tea with honey-cooked tapioca pearls.

Ingredients

Pearls

100 g large black tapioca pearls (boba, available dried at Asian supermarkets; the large variety, approximately 8–10mm diameter, is the classic size)
2 tbsp dark brown sugar or coconut sugar, for cooking the pearls
2 tbsp honey, for finishing the cooked pearls

Tea

2 tsp loose-leaf black tea (Assam or a Ceylon-Assam blend; the robust, malty style that provides the necessary strength against the milk and sweetness)
300 ml freshly boiled water, for brewing the tea

Milk

150 ml whole milk (or sweetened condensed milk diluted with whole milk for a richer result: 1 tbsp condensed milk plus 130ml whole milk)

Sweetener

1 tbsp simple syrup or honey, to sweeten the tea (adjust to taste)

Ice

ice, for shaking and serving

Method

Cook the tapioca pearls: bring a large pot of water (at least 1.5 litres) to a rolling boil. Add the dried pearls and stir immediately to prevent sticking. Cook at a vigorous boil for 20–25 minutes, stirring every few minutes, until the pearls are fully translucent throughout with no white centre when cut in half.
Drain the cooked pearls and rinse briefly with warm water. Transfer to a small bowl. Add the brown sugar and honey while the pearls are still hot and toss to coat. The sugar will dissolve into a light syrup around the pearls. Allow to cool to room temperature.
Brew the tea: steep the black tea in 300ml of freshly boiled water for 4 minutes. Strain, sweeten with the simple syrup or honey, and allow to cool to room temperature, then refrigerate until cold.
Assemble: add a large handful of ice to a cocktail shaker or large jar with a tight lid. Add the cold brewed tea and the milk. Close tightly and shake vigorously for 15–20 seconds. This both chills and aerates the drink, producing the foam on top.
Place the honey-coated tapioca pearls in the bottom of two large tall glasses (500ml capacity). Add a generous amount of ice. Pour the shaken milk tea over the pearls and ice through a fine sieve if needed.
Serve with a wide-bore straw (at least 12mm diameter is needed for the pearls to travel through easily). Insert the straw and sip: the cold tea and chewy tapioca pearls should arrive simultaneously.

Notes

The brown sugar boba variant, popularised from around 2018 onwards, uses pearls cooked and finished in pure brown sugar syrup, served in a clear glass that is first coated with brown sugar streaks before the milk (without tea) is poured over. For a matcha bubble tea, replace the black tea with a strong matcha concentrate made with 2 teaspoons of matcha whisked into 200ml of hot water and cooled. For a taro milk tea, replace half the milk with taro powder dissolved in warm water and chilled. All variants use the same pearl-cooking and shaking technique described here.
