01 - Bring 2 cups water to a boil in a small saucepan. Add the black tea bags, reduce heat to low, and simmer for 3-4 minutes. Remove from heat and let steep for an additional 2 minutes to develop full flavor.
02 - Remove and discard the tea bags. Stir in the Okinawa brown sugar while the tea remains hot, stirring continuously until completely dissolved.
03 - Pour in the milk and stir thoroughly to combine. Return to low heat and warm gently for 1-2 minutes without bringing to a boil.
04 - Pour the warm milk tea through a fine-mesh strainer into a heatproof jug or bowl to remove any tea sediment or particles.
05 - Fill two glasses generously with ice cubes. Pour the warm strained milk tea over the ice. Stir gently to combine and serve immediately while chilled.
