01 - Bring water to a boil in a small saucepan. Add tea bags, reduce heat, 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 tea bags. Stir in Okinawa brown sugar while tea is still hot, continuing until completely dissolved.
03 - Add milk and stir thoroughly. Return to low heat and warm gently for 1-2 minutes without bringing to a boil.
04 - Pour milk tea through a fine-mesh strainer into a heatproof jug or bowl to remove any tea residues.
05 - Fill two glasses with ice cubes. Pour warm milk tea over ice and stir gently. Serve immediately.
