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 2 minutes to extract full flavor.
02 - Remove and discard tea bags. Stir in Okinawa brown sugar while tea remains hot, ensuring complete dissolution.
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 to remove any tea residue.
05 - Fill two glasses with ice cubes. Pour warm milk tea over ice and stir gently. Serve immediately.
