What are boba pearls?

Boba pearls are made of tapioca starch come from cassava root (木薯). In some other cases, they are also called black pearls, tapioca pearls, or boba balls. They are the key ingredient in boba milk tea.

Boba milk tea is one of the most popular beverages now. The history of boba milk tea can be traced back to Taiwan in the 1980s when it was originally known as bubble tea. Bubble tea was created by a group of innovative Taiwanese tea shop owners who wanted to find a way to make their tea stands out from the competition. They came up with the idea of adding chewy tapioca pearls, or boba, to their tea, and the new drink quickly became a hit with customers. 

Since then, bubble tea has continued to evolve, with new and creative variations being created all the time. Today, there are countless different types of boba milk tea available, from classic milk teas to fruity and flavorful blends. And there are so many ingredients that can be combined including taro balls, sago pearls, and this boba pearls.

In Chinese, milk tea with boba pearls is called "珍珠奶茶", this shows a lovely picture of pearls in the sea. Boba pearls are super small and lovely pearls that be translucent if no coloring ingredient is added. But typically they are brown or black. In this recipe, the color of dark red boba pearls is gotten by brown sugar. Sometimes, boba pearls are also called "tapioca boba pearls" in order to separate from other milk tea ingredients made from other flour like sweet potato flour and sago.

What's tapioca starch

Tapioca starch is a gluten-free starch that is extracted from the root of the cassava plant. It is often used as a thickening agent just like cornstarch, sweet potato starch, or potato starch. Tapioca starch is also known as tapioca flour or cassava starch. When cooked, it has a slightly sweet flavor and a chewy texture. Tapioca starch is high in carbohydrates and calories, but it is gluten-free and does not contain any other major nutrients. Tapioca starch can be found in most grocery stores, and it is often used in Asian cooking.

Why use tapioca starch for boba pearls?

Tapioca starch is the perfect boba pearl base because of its sticky texture and chewy consistency. When boba pearls are cooked, they absorb the liquid that they’re in and become soft and chewy because of the high content of resistant starch. The tapioca starch makes it easier for boba pearls to hold their shape while also giving them a unique texture.

Can I use other starch?

Yes, boba pearls can be made with other starches such as potato starch. However, tapioca starch is the most popular because it creates a softer and chewier boba pearl than other starches.

What boba pearls taste like

Tapioca starch is a very strong starch, so boba pearls can be a little bit chewier. They have no taste themself, just a very faint sweetness from the starch. Very faint and you can only get it if you chew boba pearls for a long time with a focus mode. In boba milk tea, boba pearls will absorb the flavor from the syrup and milk in boba milk tea and give this drink its unique texture.

How to use boba pearls

Boba pearls are usually served cold, but can also be served hot. They are often added to boba milk tea as a topping, but they can also be used in various desserts such as boba ice cream, boba yogurt, and even boba cake!

1. the most popular way of using boba pearls is to make a boba milk tea.

2. You can add it to a smoothie.

3. Boba can also be used as a decoration for cakes, ice cream, and desserts.

Is boba pears healthy?

There are lots of discussions about where milk tea is healthy and you may also wonder whether boba pears are healthy too. Boba is made from tapioca, which is a resistant starch. resistant starch is a type of carbohydrate that is not fully broken down by the body, so it has less of an impact on blood sugar levels, but it is quite hard to digest. Another risk is the coloring ingredient used by the factory. So in general, I don't think it is very healthy food.

But one advantage of making boba pearls at home is we are much safer with the ingredients used.

Cook’s Note

About the starch

1. Tapioca starch is the most commonly used option for chewy boba pearls. In Chinese, it is called "木薯淀粉". You can get it from amazon. Currently, I have never tried other types.

2. Making part of the tapioca starch gelatinization is the best way of holding all the flour together and forming a dough for further steps.  I get several failure reports for this one, mainly caused by the over-gelatinization or lack of gelatinization.

If the starch is added directly to the boiling water or cold water, then we get a thing named non-Newtonian fluid and can't form a dough. So we add part of the starch for the gelatinization. However, if the starch is overheated or cooked, the pearls can't hold the round shape and chewy texture after cooking. Becomes quite soft and shapeless. So please follow the steps exactly. I highly suggest watching the video and reading the recipe before starting since we don't get too much time for thinking during the process.

Ingredients

Our boba pearls are made of tapioca starch, brown sugar (as a coloring), and water. Then we will coat them with brown sugar syrup to avoid stickiness.

Tapioca starch - is a gluten-free starch made from cassava root. Tapioca starch contains a large amount of resistant starch (抗性淀粉), making it the perfect ingredient for boba pearls.

Brown sugar - mainly for coloring purposes.

Water- should be cooked until boiling.

Brown sugar syrup -- to sweeten the pearls

How long can the pearls keep

The cooked pearls should be used within hours. If you want to use it next time, freeze them after the shaping.

Coloring the boba pearls

Some of the recipes may call for food coloring for example black food coloring to make the boba pearls completely black. I believe that's not so necessary. Brown sugar can give it a lovely deep brown color. But if you want to make the boba pearls more creative, there are always other options. You can use natural colors to make boba pearls in different colors. Or you can completely dismiss color ingredients and make them crystal and transparent.

Examples:

Purple boba pearls with blueberry juice

Orange boba pearls with mango/papaya juice

Green boba pearls with matcha powder

These boba drinks will not only look great but also taste delicious. Once this recipe succeeded, try to make them more interesting.

Are you supposed to swallow boba or chew it?

Boba pearls are meant to be chewed and not swallowed. While boba is safe to consume, it is not good for your digestive system as it is difficult to digest. Chewing boba releases more of its flavor in the drink while also making it easier to digest.

Instructions

In a small pot, slightly warm the water and dissolve brown sugar (or dark brown sugar).  Let the liquid boil completely over the slowest fire. Adding a cover can help to avoid too much water loss.  Add ½ of the tapioca starch in and mix well (count: 6-7 seconds). Remove from heat for the electric stove or turn off the fire, then add the remaining tapioca starch and continue mixing until gathered. Be quick during this process.

Place the remaining flour on an operation board. Transfer the smooth paste and knead it into a dough with the help of a scraper blade. At first, it might be slightly sticky. Slightly dust the board during the kneading process until it becomes smooth, not sticky anymore but still soft. 

Divide the dough into four parts and then shape one portion into a thin and long log. Cut into small cubes.

Round each small square into small balls (be patient and do not require perfect roundness). You can simply skip this process and save yourself lots of time if you get no requirement for the shape.  Longer shaping will make the balls more stable after being boiled.

On a large plate, spread some flour and coat each ball with enough flour to avoid sticking to each other. Then shift the extra starch off. You can now package them in air-tight bags and freeze them for later use.

How to cook the boba pearls

Bring a large pot of water (at least 6 times the volume of the pearls) and cook the pears for 20 to 30 minutes. Then transfer the balls into cold water (they shrink to their original size immediately). 

Drain and mix with 2 tablespoons of brown sugar syrup or honey to avoid sticky together.
