Heat 100g of milk and 50g of sugar in a rice cooker for 9 minutes to make milk tea
*It's good to buy dezawa or coffee milk instead of making black tea

After reheating, add 15g of black tea and 350g of milk, stir well, and leave it in a warm state to make it taste good

Meanwhile, put 50g of tapioca starch, 3g of cocoa powder, and 15g of sugar in a bowl
* Cocoa powder was added for black color, so you can skip it

Stir in 33g of freshly boiled hot water in a pot, little by little. Stir well with a spoon.

When it cools, knead it with your hands.

Remove the dough and make it into small grains

In the meantime, filter the tea leaves from the well-boiled milk tea after about 20 minutes. Cool it down like this
*You can make the filtered tea with milk tea one more time

Wash the rice cooker and reheat the tapioca pearl dough in 150g of hot water that is boiled enough to cover the pearls

After reheating, discard the starch water from which the pearls have been boiled, pour cold water into the boiled pearls to make them chewy, and cool them off.

Place pearls and ice in glass and fill with milk tea extract. Completion.
You can keep the remaining pearls in the freezer and reheat them
