What’s dirty boba   

Boba, also known as bubble tea or pearl milk tea, originated in Taiwan in the 1980s. It’s a delightful blend of milk tea and tapioca pearls, offering a mix of creamy and chewy textures.

Dirty boba became popular mainly because of Tiger, a famous bubble tea brand. In this type of drink, brown sugar is simmered into the thickened syrup form and can form strips on the cups of the bubble tea.

As it becomes more and more popular, lots of boba shops like Gong Cha are also providing brown sugar boba tea now.

The name “dirty” doesn’t imply anything unclean about the drink. Instead, it refers to the appearance of the drink, which often looks “muddied” or “dirty” due to the mixing of the brown sugar syrup with the milk.

Then this description evolved into different forms of attachments on the glass, which might be strawberry jam, mango jam, chocolate sauce, and even crushed Oreo. We will discover all of this one by one.

What’s the taste of dirty boba

Classic brown sugar dirty boba has a caramelized sweet and creamy taste. Other variations may have different tastes based on the milk choice (chocolate milk or match milk) and the dirty efforts ingredients. For example, if strawberries are used, the dirty strawberry boba will have a lovely strong sweet, and sour taste with fruity strawberry notes.

Why I love it

  • Most of the dirty boba can be made at home easily, requiring super simple and easy ingredients. For classic dirty boba, we need only 4 ingredients.
  • It is super enjoyable to drink the boba as it changes along with the drinking process. Different forms and statuses make it a lovely journey.
  • Most importantly, it tastes super good.  

Essential Ingredients

Boba Pearls: These are boba for this drink. Regular black boba pearls are a common choice for dirty boba.  You can make it at home, or buy a quick boba or even a instant boba which is ready to use.

Brown Sugar or brown sugar syrup : The sweetener that adds deep, molasses-like flavor.

Milk: 2% whole milk is most commonly used.  Half and Half will create an even creamy taste. For a dairy-free version, you can use almond milk, oat milk, soy milk, or any other milk of your choice for a dairy-free version.

Tea (Optional): tea base is optional. Classic brown sugar dirty boba does not contain a tea base in Taiwan. It is called tea because, in the Chinese language, tea is used to refer to drinks.  Dirty Boba sometimes includes tea, usually a strong black tea. But based on your variation options, jasmine green tea, and oolong tea has been popular choice too.

Tips about the consistency of the syrup

The thickness of brown sugar syrup for making dirty boba can vary depending on your plan to serve your dirty boba. If the warm versions, the syrup will melt quickly, so a thicker texture is recommended.

For iced dirty boba, just make sure the syrup is thick enough to coat the back of a spoon. This ensures that the syrup will stick to the surface of the serving glass. Adding ice cubes can help it to form a dirty appearance.

You can see in the two pictures below. Different consistencys of the brown sugar syrup will create different dirty patterns on the glass. So which one is your favorite?
