Cook hot water and brew the assam tea for 5 minutes.

Let it cool down. While that, slice the lemon for garnish and squeeze the lemon juice.

Make sugar syrup with one to one ratio. 100 gr sugar and 100 ml water on a pot and cook it until sugar dissolved and a bit thickened.

Get a long glass. Fill up ice, sliced lemon, ice and slice lemon until full.

Pour the sugar syrup and the cold assam tea. Garnish with some mint leaves.
