Ingredients:
- 1/2 cup Water (for the hot dough)
- 1/4 cup Dark Brown Sugar or Muscovado (for the hot dough)
- 1 1/2 cups Tapioca Starch (Pure Starch), plus extra for dusting
- 1 cup Water (for the syrup bath)
- 1/2 cup Dark Brown Sugar, packed (for the syrup bath)
Instructions:
- In the medium saucepan, combine the 1/2 cup of water and 1/4 cup of brown sugar. Bring the mixture to a rolling boil over medium-high heat, stirring until the sugar is completely dissolved. Remove from heat immediately.
- Place 1 1/2 cups of tapioca starch into the large mixing bowl. Immediately pour about 3/4 of the boiling sugar liquid directly into the starch. The starch should look wet and clumped, like heavy wet sand.
- Quickly use a sturdy silicone spatula to mix the scalded starch. Add the remaining hot liquid one tablespoon at a time only if dry patches remain, until a shaggy, pliable dough forms.
- Turn the dough out onto a work surface dusted with tapioca starch. Knead the dough vigorously for 5–7 minutes while it is still warm until it is smooth, uniform, and resembles firm playdough. It should not be sticky. Cover the dough tightly and let it rest for 10 minutes.
- Dust your rolling surface lightly with tapioca starch. Line a baking sheet with parchment paper. Divide the dough into four equal pieces, keeping unused portions covered. Roll one piece into a long, thin rope, roughly 1 cm (3/8 inch) in diameter.
- Use a sharp knife to cut the rope into small, even pieces (about 1 cm cubes). Roll each cube quickly between your palms or fingertips into a small, smooth sphere, aiming for consistent size. Lightly dust the finished pearls with tapioca starch and place them on the lined baking sheet.
- Bring a large pot of water (about 8 cups/2 litres) to a rapid, rolling boil. Gently drop the raw pearls into the boiling water, stirring gently at first to prevent sticking to the bottom.
- Once the pearls float to the surface, reduce the heat slightly to maintain a rolling simmer. Cook for 15–20 minutes until mostly translucent. Turn off the heat, cover the pot, and let the pearls steep in the residual hot water for 15 minutes.
- Drain the pearls using a slotted spoon or sieve. Immediately transfer them to an ice bath for 30 seconds to stop the cooking process and enhance the chewiness. Drain well.
- In a separate saucepan, combine the 1 cup water and 1/2 cup brown sugar (for the Syrup Bath ingredients). Bring to a simmer until the sugar is dissolved and the syrup is slightly thickened (about 5 minutes).
- Add the rinsed boba pearls to the warm brown sugar syrup. Let them sit and soak for at least 15 minutes before serving. Serve warm or at room temperature with milk tea.
