01 - Bring water to a boil in a small saucepan. Add tea bags, reduce heat to low, and simmer for 3–4 minutes. Remove from heat and allow to steep for an additional 2 minutes to develop full flavor depth.
02 - Discard used tea bags. Stir Okinawa brown sugar into the hot tea until completely dissolved, ensuring even sweetness distribution throughout the liquid.
03 - Pour in the milk and stir thoroughly to combine. Return mixture to low heat and warm gently for 1–2 minutes without reaching a boil to maintain silky texture.
04 - Pour the warm milk tea through a fine-mesh strainer into a heatproof jug or bowl to remove any tea sediment or particles, ensuring a smooth consistency.
05 - Fill two glasses generously with ice cubes. Pour the strained warm milk tea over the ice, stir gently to blend temperatures, and serve immediately while chilled.
