How to make bubble tea

For the dark brown sugar syrup

  • STEP 1

    Put the teabags or tea leaves in 100ml boiling water and leave to brew for 10-15 mins. Discard the teabags or tea leaves, then set the tea aside to cool to room temperature. To make a clear sugar syrup, stir the caster sugar with 60ml water in a small saucepan over a medium heat and bring to the boil. Remove from the heat and leave to cool.

  • STEP 2

    Bring 500ml water to a rolling boil in a small saucepan set over a medium heat, then add the tapioca balls. Using a rubber spatula, stir the water and make sure the balls, or boba, are not sticking to the side of the pan. Turn the heat up to reach a rolling boil for 2 mins, then turn off the heat, but keep the pan on the stove with a lid on for another 2 mins. Drain the boba in a sieve under gentle running tap water for about 20 seconds to slow down the cooking. Using the same spatula, gently push the boba around in the mesh to make sure they don’t stick and are cooling down evenly. Once they’re cool to the touch, set in a mixing bowl, add the 1 tsp dark brown sugar and mix in thoroughly.

    To make the sugar syrup, add the 50g dark sugar to 60ml water in the same pan set over a medium heat. Slowly stir and let it come to a boil, making sure all the sugar has dissolved. Turn off the heat and leave to cool down. It will thicken as it cools. This will make approx. 80ml syrup, about 2½ servings. Any leftover syrup will keep in a jar in the fridge for up to a month. Add the cooked boba and mix until thoroughly coated. The boba can be left covered for up to three hours. Do not refrigerate as they will harden.

    Assemble the bubble tea. Put the sweetened boba in a 485ml drinking glass, or two smaller glasses if you want to share. Swirl the boba to create a marble effect on the wall of the glass. Pour in the brewed tea and 1 tbsp of clear sugar syrup. Add ½ cup of ice and, using a metal spoon, stir the glass so the syrup and the tea are thoroughly mixed but make sure you don’t scrape off the sticky marbling effect on the wall of the glass. Top up with 200ml of cold milk and serve with a boba straw.

What is bubble tea?

Bubble tea or boba tea is a tea-based drink that originated in Taiwan in the 1980s. It is commonly known to be served with sweetened milk and chewy tapioca balls in a sealed plastic cup with an extra-large straw. I grew up drinking boba tea and always found it funny that I had to drink and chew at the same time.

There is a debate on who actually invented boba tea. One story says the owner of the Chun Shui Tang tea room, a tea house in central Taiwan city Taichung, claimed he got the idea of serving cold tea when he noticed coffee being served cold while on a visit in Japan. Then one day, during a staff meeting, his product development manager poured some prepared tapioca balls into her drink and the very first boba tea was born. The other story is from another tea room, the Hanlin Tea Room of Tainan, the southern part of Taiwan, where the owner said he was inspired when he saw white tapiocas on sale in a local market. He decided to mix it with tea and created ‘pearl tea’.

There are different sizes of tapioca balls. The large dark-coloured ones are called boba and the smaller ones, which could either be white or amber-coloured, are called pearls. The names are interchangeable these days depending on who you ask and where they’re from. In Taiwan, it’s a north and south thing. In the US, it could be a west coast versus east coast thing. Even in California alone, the north and south have their own preferences. There is even rumour that the word ‘bubble’ in bubble tea doesn’t refer to the toppings at all, and that instead it’s because of the foam that forms when you shake the milk.

What kind of tea do you use for bubble tea?

Traditionally, black tea is the preferred choice. Personally, I still prefer black tea. In any reputable bubble tea shop, you have all types of tea available. Assam is very often used as the standard, but some tea is better to drink cold and mixed with milk. For example, for something light, green tea, jasmine tea, oolong, Assam and Darjeeling are all good options. For something with a bit more body and oomph, you can choose English breakfast, matcha or pu’er tea. If you prefer something with some more flavour, Earl Grey or masala chai will work well.

What kind of milk do you use for bubble tea?

Whole milk is always the best choice, not just for flavour but, when you shake it, it foams up the best. Nowadays, some places do have non-dairy options like soy or almond. I can’t say if non-dairy milk would work because I’ve never tried it myself. In Taiwan, you often have to pay extra for ‘real milk’ because many places would use milk powder or creamer because it is much cheaper.

What kind of sweetener do you use in bubble tea?

Traditionally, sugar syrup is used in the milk and I still prefer that over a spoonful of caster sugar, because the sugar has to dissolve and sugar syrup distributes quickly and evenly. In our recipe, we prepared two different types of syrup. One is a clear sugar syrup to flavour the milk tea and one is a dark brown sugar syrup to flavour the tapioca. The latter is a much more recent development as the dark sugar syrup creates a marbling effect with the milk. One of the most popular options in the last few years is the brown sugar boba tea, which actually does not contain any tea. It is brown boba gently cooked in caramelised brown sugar, topped with ice and milk then shaken.

Other sweeteners can be used such as honey, maple syrup and, one of the favourites in any Asian pantry, sweetened condensed milk.

One of the best things about boba/bubble tea is how customisable each drink can be. You can have it with 50%, 30% or zero sugar; you can choose how much ice there is; and you can have no topping or all the toppings you desire.

Top tips for bubble tea

  1. If you want to have a foamy effect, add the tea, syrup, milk and ice in a shaker and shake for 6 seconds. Then, add everything into the glass with the syrup boba.
  2. Use milk without any tea for an extra creamy taste.
  3. You can substitute sugar syrup with honey, caster sugar, light-brown sugar or agave syrup.
  4. It’s best to use quick-cook or pre-made boba to save time.
  5. Only cook enough boba for the amount you are serving, as the shelf life of cooked boba is only about 3 hours.
  6. Never refrigerate cooked boba – drink boba tea fresh. The longer boba sit in something cold, the quicker they will harden.
  7. The best thing about homemade boba tea is you can adjust the sweetness, the amount of ice or even the style of tea, so get creative to suit your taste.
