Prepare the sugar syrup by boiling a half cup of water in a saucepan over medium heat. Add the brown sugar and stir until completely dissolved. Remove from heat and let it cool down.
Bring 2 cups of water in a boil. Transfer water in a teapot or large cup. Add tea bags and steep as directed in the packet instruction. Steep it longer for a stronger flavor. Chill the tea before using.
Pour the prepared tea into 2 tall glasses and add the tapioca pearls. Add milk and syrup as preferred. Add crushed or cubed ice if desired.
Notes
You can skip the milk and add fruit juice or nectar instead if you prefer a fruity-flavored tea instead.
