Thai Bubble Tea is a beverage made with black tea, sweetened condensed milk, and tapioca pearls. The tea is brewed and then mixed with sweetened condensed milk to create a creamy and sweet flavor. The tapioca pearls are added to the bottom of the cup and then the tea is poured on top, creating a unique and delicious drink. The tapioca pearls in Thai Bubble Tea are the key ingredient that sets this drink apart from other teas. The pearls are made from tapioca starch and have a chewy texture that adds a fun element to the drink. They can be black or white and vary in size. The pearls are cooked in boiling water until they become translucent and soft. They are then rinsed and coated in a syrup to give them a sweet flavor.
