Add the 2 cups of water in a large mixing bowl. Shell the Tamarinds, make sure to remove the veins. Only keep the pods with the "sticky" fruit and place them in the water, let them sit for 2 hours.

Occasionally stir the water and sort of rub the pods while emerged. The fruit of the Tamarind will melt into the water, leaving only the seeds covered in their skins.

Strain the water into another bowl after the has passed. Add the sugar, mix and taste. Add additional sugar if you please.

Pour into a pitcher or bottles and place in the fridge for at least 3 hours. If you can't wait, just pour this juice over ice. The juice will keep for a week in the fridge, be sure to stir/shake before serving.
