The "pearl" in bubble tea is generally black, and its shape is very round and smooth, and it tastes elastic, so it is called "pearl".

Pearls are generally made from cassava flour, which is the starch extracted from the root tuber of Euphorbiaceae cassava. When heated with water, it will be transparent, and the taste is very soft and elastic.

Bubble tea has no cassava flour, so what can be used instead of other starches?

The main component of cassava flour is cassava starch. If there is no cassava flour, it is suggested that corn starch, sweet potato starch, potato starch and other starches can be used instead, so that "pearls" can also be made.

However, compared with other starches, tapioca flour is more sticky and tastes q-elastic, while pearls made from other starches may not taste as soft and waxy as those made from tapioca flour.

3 whether boiled pearls are boiled under boiling water or cold water.

When cooking pearls in bubble tea, it is generally necessary to boil water, so that the starch on the surface of pearls can be quickly solidified by heating. When the pearls are cooked to float on the water, the fire can be turned off. At this time, you can cover the pot and stew them properly, so that the boiled pearls will not taste raw.

But if it is cold water, then the starch on the surface of the pearl will easily melt into the water, and at this time, the pearl will become smaller and smaller, and it is not easy to be cooked.

4 How long does it take to cook the pearls thoroughly 15-20 minutes or so.

The main component of pearls is starch, which is difficult to cook. Generally, it takes about 15-20 minutes to be thoroughly cooked. At this time, pearls will float on the water and show a transparent appearance.

If the cooking time is too short, then the pearl may not only have a "raw" taste, but also cause a greater burden on the gastrointestinal digestive system of the human body, which is easy to cause indigestion symptoms such as abdominal pain, abdominal distension and constipation.
