For how to make brown sugar boba milk at home, use a small pot and heat up the water and brown sugar on a low heat. The low heat ensures little loss of water. Keep cooking until the sugar is dissolved completely and stir occasionally. Continue heating the liquid until it is boiling.
Add in half of the starch and mix rapidly. This should take about 7 seconds. Remove from the fire and add in the rest of the starch. Combine quickly.
Coat a cutting board with flour and move your starch paste over there knead it into a ball of dough. Keep kneading until it becomes smooth, and be sure to work quickly. If you allow the dough to cool down all the way, it will become difficult to work with.
Cut your dough into four approximately equal portions. Cover the three you are not using with a plastic bag and shape your active portion into a lengthy log. Dice the log into small cubes.
Take each of the squares and round them into small balls. Then, spread some flour on a play coat each of the balls with flour, using enough to keep them from sticking together.

To make this work, take 2 slices of the brown sugar slab and a cup of brown sugar and melt them in a small pot with 100 milliliters of water. Keep heating until large bubbles form. You can skip this entire step and just use brown sugar syrup, if you wish.
To cook the boba pearls, boil enough water to make up six times as much water as there are pearls to cook. Cook your pearls for about 25 minutes. From there, move the balls into cold water. This will cause them to shrink. Use running water to wash the pearls and then drain them. Mix in 2 tablespoons of honey, sugar, or brown sugar syrup. You want to add it from sticking together.
