01 - Bring water to a boil in small saucepan. Add tea bags, reduce heat and simmer 3-4 minutes. Remove from heat and let steep additional 2 minutes to extract full flavor.
02 - Remove and discard tea bags. Stir Okinawa brown sugar into hot tea until completely dissolved, ensuring even sweetness distribution throughout the liquid.
03 - Add milk and stir thoroughly. Return to low heat and warm gently 1-2 minutes without boiling to preserve milk texture and prevent separation.
04 - Pour milk tea through fine-mesh strainer into heatproof jug or bowl to remove any remaining tea particles or residue for smooth consistency.
05 - Fill two glasses generously with ice cubes. Pour warm milk tea over ice and stir gently to chill. Serve immediately while still cold.
