What is Tapioca Made of in Bubble Tea?

6 Key Facts: What is Tapioca Made of in Bubble Tea?

Bubble tea, a sweet and refreshing beverage, has seen a surge in popularity across the globe. Often, people find themselves sipping on this delectable drink without knowing what gives it its distinct chewy texture.

The magic ingredient is tapioca, a starch that is the backbone of those delightful pearls bobbing at the bottom of bubble tea.

These pearls, often referred to as boba, are created using starch derived from the cassava root. This plant, natively from South America, has become a fundamental ingredient in various Asian culinary traditions.

To understand the anatomy of delicious bubble tea, it’s essential to peer into its main ingredients. A typical bubble tea consists of a tea base, usually black or green tea, that is blended with milk or fruit flavors to create a variety of tastes.

I still remember my first time trying boba tea; the chewy texture of tapioca pearls combined with the sweet and creamy tea created an experience like no other.

The key to a delicious bubble tea lies not only in the quality of the tea and the flavorings but also in the freshness and consistency of the tapioca pearls that we so enjoy.

1. What Are Tapioca Pearls?

If you’ve ever sipped on bubble tea, you’ve encountered those fun, chewy balls at the bottom of your cup. Those are tapioca pearls. They are the heart of the bubble tea experience.

Tapioca comes from the starch obtained from cassava roots, a plant native to South America that made its way across the globe. When I think of tapioca pearls, I picture them almost like playful, tiny edible marbles. 

Making these pearls starts off with the tapioca starch, which turns into a dough-like state before it’s rolled and cut into little balls. The starch from the cassava root is quite similar to the potato starch of the sweet potato.

These pearls then take a dip in boiling water, which softens them and makes them splendidly springy. While they’re naturally quite bland, they soak up any sweet or flavorful liquid they swim in.

Typically, they bask in a bath of brown sugar or honey before joining your drink, taking on a sweet taste and a glossy look.

When you scoop them up with that big straw, they pop into your mouth with a satisfying squish! And, oh, the contrast of textures between the tea and the pearls! It’s textural bliss.

Let’s summarize: what is tapioca made of in bubble tea?

In a nutshell, tapioca balls/pearls are the starch from cassava, turned into chewy, sweetened balls that make bubble tea an adventure in every sip. No gelatin is involved, so they suit vegans just fine.

2. Origin and History

Bubble tea, with its chewy tapioca pearls, has an intriguing backstory that began in East Asia. Tapioca itself comes from the cassava plant, a staple in South America, but its journey to becoming a tea sensation started in Taiwan.

Discovery of Tapioca

Tapioca is a starchy extract from the cassava root, which is native to South America. I find it fascinating that cassava flour made its way to East Asia, where inventive minds transformed it into the tapioca balls we love today.

These pearls became a signature ingredient in Taiwanese tea stands, baked and boiled to achieve the ideal springy texture.

Bubble Tea Evolution

Taiwan takes the stage as the birthplace of bubble tea in the 1980s. The drink was a game-changer, combining sweetened tea with milk and these delightful pearls.

Taiwanese tea stands began serving up this unique concoction, and quickly, bubble tea swept across East Asia; it didn’t take long for it to make a splash in Hong Kong and beyond.

The drink’s evolution saw variations in tea bases, flavors, and toppings, making it a global phenomenon.

Bubble tea’s appeal lies in its playful combination of textures and the interactive experience of “chewing” your drink.

Its simplicity belies the intricate history of cultural exchange and innovation that led to the creation of this beloved beverage.

3. Bubble Tea Ingredients

Making bubble tea is always a fun adventure in the kitchen. I mix tea, sweeteners, and other tasty bits to create something truly delightful.

Tea Varieties

Tea is the backbone of any bubble tea. I often use black tea as it adds a strong, robust flavor. However, green tea works great when you want something lighter.

There is a type of tea to suit anyone, as there are so many to choose from, but most times, it’s between these two. Fruit teas are my go-to when I’m in the mood for something fruity and fun.

Sweeteners and Flavors

I love adding a little sweetness to my bubble tea. Dark brown sugar and brown sugar syrup are my favorites for their rich flavor.

Sometimes, a splash of fruit juice lifts the taste and brings a surprising twist. Whether it’s a classic pearl milk tea drink or something more exotic, the right sweetener can make all the difference. 

Of course, you can adjust this to how you like it, just like how they ask at bubble tea shops whether you’d like normal, half, or no sugar.

Additional Toppings

For me, the best part of bubble milk tea is the gelatinous texture of the tapioca balls. These little pearls are the stars of the show, adding a fun chewiness to every sip.

4. How To Make Tapioca Pearls

Making tapioca pearls for bubble tea can be exciting and rewarding, especially when I get to enjoy my own boba pearls with their unique, chewy texture.

Let’s dive into how to craft these sweets for a delightful tea experience.


  • Tapioca starch (also known as tapioca flour)
  • Brown sugar (or white sugar for clear boba pearls; muscovado or dark brown sugar for a richer taste)
  • Water
  • Dark cocoa powder (for black tapioca pearls) or matcha powder (for green tapioca pearls), optional


  • Saucepan
  • Whisk
  • Smooth work surface for kneading

Making the Starter Dough

  1. Prepare Ingredients: Measure out the tapioca starch, sugar, and water. Decide if you want to make clear, green, or black tapioca pearls, and choose your sugar and optional powders accordingly.
  2. Cook Sugar Water: In a saucepan, heat the water and sugar. Do this over medium heat, bringing it to a boil while making sure the sugar is fully dissolved. (Incorporate black food coloring into the boiling water prior to mixing it with the starch. This gives the pearls its distinctive appearance, eliminating the need for dark cocoa powder.)
  3. Add Tapioca Starch: Once boiling, add a portion of the tapioca starch to the boiling water. Whisk until smooth. 
  4. Thicken the Mixture: Continue cooking over low heat until it forms a thick paste. This is your starter dough.

Making the Tapioca Pearl Dough

  1. Combine with Tapioca Starch: Transfer the starter dough to a mixing bowl. Gradually add the remaining tapioca starch, mixing until a starchy dough forms.
  2. Knead the Dough: Put the dough onto a smooth work surface. Knead while hot until smooth and not too sticky. If the dough is too wet, sprinkle a little more tapioca starch as needed.
  3. Test the Texture: The dough should be smooth and slightly sticky but should come off cleanly when lifted.

Shaping the Boba Pearls

  1. Shape Pearls: Take small pieces of dough and roll them into balls between your palms. Alternatively, roll the dough flat, cut into squares, and then roll these into balls. To prevent drying, you should keep the dough covered in a plastic wrap.
  2. Prevent Drying: Keep unused dough wrapped in plastic to avoid drying out while shaping the pearls.

Cooking the Boba Pearls

  1. Boil Water: For every cup of boba pearls, use 4 cups of water. Bring to a boil.
  2. Cook Boba Pearls: Add the boba pearls to boiling water and cook until they are soft and almost translucent. Fresh pearls cook faster than dried ones.
  3. Cool in Cold Water: Once cooked, strain and immediately dunk the pearls in cold water to stop them from sticking together.

Making Sugar Syrup

  1. Prepare Sugar Syrup: In a separate saucepan, dissolve brown sugar or white sugar in water to make a syrup. For added flavor, use molasses-rich brown sugar.
  2. Final Cook: Transfer the cooled and cooked pearls into the sugar syrup. Cook for a few minutes to allow the pearls to absorb some sweetness.

Serving Suggestion

Serve your homemade tapioca boba pearls in your favorite tea or beverage for a delicious treat. Remember, homemade boba pearls are best enjoyed fresh for their unique chewy texture and flavor.

Lastly, enjoy your homemade boba pearls; making bubble tea at home is a fun adventure into the world of delicious and chewy beverages. 

When you craft your own tapioca pearls and experiment with various milky or fruity mixtures, you’ll feel pretty accomplished. 

To be able to make your favorite boba tea at home of the same quality or better than what you would usually buy from a shop will always give you a happy feeling right in the comfort of your own place. 

5. Assembling Bubble Tea

When making bubble tea, the key to a delicious cup lies in layering flavors and textures to create a unique drink.

From the bouncy chewiness of tapioca balls to the sweet creaminess of the tea, each element combines to delight the senses.

Layering the Ingredients

Start by adding cooked, chewy tapioca pearls to the bottom of a clear glass. Boba balls, or tapioca pearls, are the stars of the show, providing that signature chew with each sip. 

Room temperature pearls work best as they are soft and chewy.

On top of the pearls, pour ice cubes to chill the mix. Next comes the tea, poured gently over the ice—using either cold tea or hot tea that has been cooled to the right temperature, ensuring it doesn’t melt the ice quickly. 

Lastly, add milk to balance out your boba milk tea and stir.

Adjusting Sweetness and Texture

Sweetness varies by personal preference, so I adjust mine by drizzling in simple syrup. This sweetener dissolves easily, which makes it perfect for blending smoothly into the drink.

Each component, from the syrup to the milk, alters the drink’s profile and mouthfeel. My aim is to balance these additions until I get my perfect cup of bubble tea, tailored just for my taste buds.

6. Health Benefits and Dietary Considerations

In bubble tea, tapioca adds a chewy texture and sweetness. I’ll talk about the numerous health benefits, calories, and possible allergies so you know just what’s in your cup.

Rich in Iron

Tapioca is a beneficial source of iron, a crucial element for the production of hemoglobin.

A lack of iron may result in anemia, which manifests through symptoms like tiredness, difficulty breathing, and chest discomfort, especially common in pregnant women.

Sodium Levels

With low sodium content, tapioca pearls help in avoiding the risks associated with high sodium intake, such as high blood pressure and cardiovascular issues.

A one-cup serving of tapioca pearls provides only 1.52 milligrams of sodium, supporting heart health.

Digestive Comfort

These pearls are known for their gentle nature on the digestive system, ensuring ease of digestion for those who consume them.

Although there have been cases of over-consumption where people have had way too many tapioca pearls, resulting in an operation to remove them from the stomach, so don’t overdo it!

Adaptable for Various Dietary Needs

For individuals with dietary restrictions, tapioca pearls stand out as an excellent choice. They are inherently free from gluten, making them safe for those with allergies or sensitivities to wheat, grains, and gluten. Additionally, being dairy-free, they cater well to vegan diets.

Calcium Content

Offering a source of calcium, tapioca contributes to the maintenance of strong bones and teeth. Calcium plays a crucial role in several bodily functions, including nerve communication, blood clotting, and the regulation of muscle and blood vessel contractions and dilations.

A single cup of tapioca pearls contains 30.4 milligrams of calcium.

Caloric Content

The tapioca pearls found in bubble tea are rich in carbohydrates and calories, with a 100-gram serving typically offering a significant energy boost, primarily derived from starch.

Love bubble tea? Remember, it often has a lot of sugar, which increases the calorie count, so enjoy it in moderation!

Drinking Experience

Sipping on boba tea offers a delightful blend of flavors and textures, turning each beverage into an exciting experience.

The Chewiness Factor

The chewy pearls add a surprising twist to the standard milk tea beverage. These pearls, made of tapioca, give bubble tea its distinctive chewy consistency that’s both delightful and fun to eat.

I find the chewy boba offers a playful contrast to the drink’s liquid base, whether that base is the classic milk tea or a fruit-flavored concoction.
