Pearl Milk Tea (Bubble tea), also known as Boba Milk Tea, referred to as Jen's Milk, is a tea drink circulating in Taiwan, after adding powdered dough to milk tea, it becomes pearl milk tea. It is quite popular among teenagers because of its special taste.

Pearl milk tea is one of Taiwan's "bubble tea" culture, although only in the milk tea added tapioca, but has become one of Taiwan's most representative drinks and snacks.

There was only one name for it in the early days. Around 1988, a vendor named "Grasshopper" on Hai'an Road in Tainan City, inspired by actress Fiona Yip at the time, changed the name of pearl milk tea to boba milk tea. Later in Southern Taiwan, the term "boba" was used to refer to large pink rounds and "pearl" to refer to small pink rounds. With the chain stores in Southern Taiwan expanding to the north, this categorization has been gradually accepted by Taiwan residents.

Outside Taiwan, it is also common to see the term "BOBA" or "Bubble". The reason for this is that new Taiwanese immigrants to North America in the late 1980's still used the term "boba milk tea" as a rallying cry, and as a result, "BOBA Tea House", "BOBA Planet", "BOBA World" and other tea houses sprang up all over California, and the current non-Taiwanese residents still use the term "BOBA" or "Bubble" all the time. They will say in English to the waiter at the counter: "Give me latte, and add some BOBA in, please." (Give me a cup of latte, and add some "boba"), "boba" has also become synonymous with powdered doughnut.

Pearl Milk Tea generally use larger particles of powder round, after cooking the diameter of about 7 millimeters or more, otherwise the diameter is too small is easy to mouth full of pearls, but also not convenient to swallow and chew. But most of the pearl milk tea merchants still have to provide small powder round pearl. Of course, there is also a kind of "amber pearl" this kind of pearl is made of 100% brown sugar.
