01 - Bring 2 cups of water to a boil and steep the black tea bags or loose tea for 5 minutes. Remove the tea bags or strain out the leaves. Set aside to cool completely.
02 - Prepare the quick-cook tapioca pearls according to the package directions. Drain and rinse under cold water to stop the cooking process. Set aside.
03 - In a small saucepan, combine the blueberries, sugar, 2 tbsp water, and lemon juice. Simmer over medium heat for 5–7 minutes, stirring gently, until the berries burst and the mixture thickens. Mash the berries and press through a fine mesh strainer to yield a smooth syrup. Allow to cool.
04 - Divide the cooked tapioca pearls evenly between two tall glasses. Fill each glass with ice cubes.
05 - Pour 2–3 tbsp of the blueberry syrup into each glass. Add half of the cooled brewed tea and half of the cold milk to each glass. Stir gently to combine.
06 - Taste and adjust sweetness with honey or your preferred sweetener, if desired. Serve immediately with wide boba straws.
