Boil 1 liter of filtered water in a large pot or kettle. Ensure the water is fresh and clean for the best taste.

Add 2 teaspoons of loose-leaf black tea or 2 tea bags to the boiling water. If using loose-leaf tea, you can use a tea infuser or strainer to make it easier to remove the leaves later.

Reduce the heat to a simmer and let the tea steep for 3-5 minutes, depending on your desired strength of tea. For a stronger tea, steep for the full 5 minutes.

Remove the tea leaves or tea bags from the water. If using loose-leaf tea, carefully pour the tea into another container through a strainer to catch the leaves.

While the tea is still warm, add 1-2 tablespoons of jaggery or honey. Stir well until the sweetener is completely dissolved. Adjust the amount of sweetener to your taste.

If desired, add the juice of 1 lemon to the tea for a hint of citrus flavor. Stir well to combine.

Allow the tea to cool to room temperature. This step is important to prevent the tea from becoming cloudy when chilled.

Once cooled, refrigerate the tea until it is chilled. You can speed up the chilling process by adding ice cubes made from filtered water.
