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. Once cooked, drain and rinse under cold water to stop the cooking process. Set aside.
03 - In a small saucepan, combine the blueberries, sugar, 2 tablespoons of water, and lemon juice. Simmer over medium heat for 5 to 7 minutes, stirring gently, until the berries burst and the mixture thickens. Mash the berries with a spoon, then strain through a fine mesh strainer to obtain 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 to 3 tablespoons of the blueberry syrup into each glass. Add half of the cooled brewed tea to each glass, followed by half of the cold milk. Stir gently to combine all layers.
06 - Taste and adjust sweetness with honey or your preferred sweetener if desired. Serve immediately with wide straws for the boba pearls.
