- 4 cups boiling water
- 1/4 cup firmly packed light brown sugar
- 2 to 3 tablespoons minced crystallized ginger
- 2 tablespoons tamarind paste
- 1 tablespoon fresh lemon juice, or more to taste
- Fresh mint sprigs, for garnish
In a bowl, whisk together the boiling water, brown sugar, ginger, and tamarind paste until the mixture is combined well. Let steep for 5 to 6 minutes, then add the lemon juice and let the mixture cool. Strain it through a fine sieve set over a pitcher and chill for 2 to 3 hours. Divide the cooler among tall glasses filled with ice cubes and a mint sprig.
