Brew tea bags with 260ml water, allowing tea bags to steep in hot water for at least 2 minutes.
Get a tall glass, put in the brown sugar syrup, fill the glass with ice cubes. Pour in the evaporated milk into glass, then lastly pour in the tea.
And voila, you'll your 3-layer tea. Due to the density of each layer, they create separate layers of different colors. Don't forget to take a picture before you stir it. Enjoy!
