Why are all the pearls in milk tea black?

Because the source of black is caramel, it is added to increase the sweetness of pearls. The "pearl" for bubble tea is made of sweet potato powder, which is usually soaked in syrup before adding milk tea to ensure that sweet potato powder can still maintain its sweetness in sweet milk tea.

Black tea is usually used as the base of milk tea, but some shops also offer green tea and bubble tea. There are also many shops that add coffee jelly, tofu, pudding, grass and other similar foods to milk tea, so that guests can choose freely to add flavor.

The origin of foam tea:

There was only one name in the early days. About 1988 A street vendor named "Cao Meng" in Hai 'an Road, Tainan City took the inspiration of actress Ye Zimei at that time and renamed bubble tea Boba milk tea. Later, in South Taiwan Province Province, the saying that Boba refers to a big pink circle and Pearl refers to a small pink circle is increasingly emerging. With the chain stores in South Taiwan Province Province moving northward, this classification is gradually accepted by residents in Taiwan Province Province.

Outside Taiwan Province Province, the word Boba or Bubble is also common. The reason is that the new immigrants from Taiwan Province who came to North America at the end of 1980 still called for "Boba milk tea", resulting in teahouses like Boba Teahouse, Boba Planet and Boba World springing up all over California. At present, non-Taiwan Province residents are still full of "bobbers" or "bubbles".

Generally, powder balls with larger particles are used to make tea, and the diameter after boiling is about 7 mm or more. Otherwise, if the diameter is too small, it is easy to swallow beads, and it is not convenient to swallow and chew. But most tea makers still provide small round pearls. Of course, there is also a kind of amber pearl, which is made of 100% brown sugar.
