Use a tea filter to brew the tea by placing the Thai tea mix into the filter and pouring hot water over it. Let it steep for a few minutes. If you find yourself without a tea bag filter, steep the tea directly in hot water for 3-5 minutes, then strain it through a fine mesh strainer.
Add squeezed lime juice. If you prefer a sour taste, feel free to add more squeezed lime juice until it reaches your desired flavor. Stir and combine the ingredients thoroughly; you’ll notice the color changing a bit lighter.
