Peel 1 lb of fresh tamarind from its shells. Discard the shells.
Add 4 cups of water, 2 cups of sugar, and 1 lb of fresh tamarind to a 4 quart sauce pan and bring to a boil. Once the mixture comes to a boil, reduce the heat to medium-high. Continue to cook all ingredients on the medium-high setting for 30 minutes .
Allow the mixture to cool for 30 minutes to one hour. After the syrup cools, use a colander to remove the cooked tamarind and its seeds. Reserve the syrup in a 4 liter bowl or similar container.
Using your hands, remove the seeds from the tamarind pulp. Discard the seeds and add the pulp to the syrup reserved in the 4 liter bowl.
Blend the pulp and liquid using a hand blender or similar device. Blend both ingredients until smooth.
Once the mixture is fully blended, strain the syrup using a colander. Use a spoon to help push the syrup through the mesh colander. Reserve the syrup in a 4 liter bowl. Discard the pulp that does not strain.
Tamarind Syrup is ready to use for your cocktail or dessert! You can also store the remaining syrup in Mason Jars or freeze in a ice cube tray.
