Bring water to a boil. Turn off the heat, add Thai tea bags into the pot and let sit for 5 minutes. After 5 minutes, discard the tea bags.
Add sweet condensed milk. Stir to combine.
Add ¾ cup to 1 cup of sugar. Stir until sugar dissolves. Taste it to see how you like it. Just remember one thing, when it's hot, it tastes less sweet.
Refrigerate and chill for at least 1 hour. Serve over ice. Enjoy!
Notes
If you can not find individual Thai tea bags, use 10-12 tablespoons and filter through a mesh strainer or cheesecloth.
