To prepare the tapioca pearls for the boba, start by boiling water in a medium-large saucepan.
Add the uncooked black tapioca pearls and reduce the heat to only below medium. Allow the pearls to simmer for 15-30 minutes, stirring even times to prevent sticking.
The cooking time will vary based on the type of pearls used, so refer to the package instructions.
Meanwhile, prepare the simple syrup. Done by whisking together cane sugar and water in a small saucepan. Simmer for about 3-5 minutes or until the sugar dissolves completely.
Reserve 3-4 tablespoons of the simple syrup and add the rest to a medium mixing bowl.
After the tapioca pearls are cooked. You can strain them through a fine-mesh strainer, and rinse them lightly. And transfer to the mixing bowl with the simple syrup.
Mix well to ensure that the pearls coats with syrup and let them soak for 30-40 minutes.
For Thai tea, add filtered water, and loose-leaf black tea along with star anise, cardamom, and turmeric in a medium saucepan. Bring to a simmer for 5 minutes.
Once steeped, strain the tea into a heat-safe container. Add the reserved simple syrup, and stir to combine.
