Bubble tea (also known as pearl milk tea, bubble milk tea) Recipes contain tea of some kind, flavors of milk, as well as sugar (optional). Toppings, such as chewy tapioca balls, popping boba, fruit jelly, grass jelly, agar jelly, and puddings are often added. Ice-blended versions are frozen and put into a blender, resulting in a slushy consistency. There are many varieties of the drink with a wide range of flavors. The two most popular varieties are black pearl milk tea and green pearl milk tea. It is particularly rich in antioxidants and vitamins. It is found to improve our immune system, to control blood sugar levels, reduce damage to cells and prevent cardiovascular diseases.
