Watermelon Tarragon Agua Fresca

1. You will probably need to make the agua fresca in two batches, depending upon the size of your blender. Blend together all of the ingredients except the sparkling water (or club soda).
2. Chill the blended ingredients for at least 30 minutes, this allows the flavors to marry as well as get nice and cold.
3. Pour the cooled agua fresca through a strainer into a pitcher. Add the sparkling water (or club soda) right before serving (if you won’t be serving the whole batch immediately, then add 2 ounces of the sparkling water to each glass instead of the whole pitcher) .
4. Pour a little sugar into a saucer or shallow bowl. Wet the rim of each glass with a little lemon juice, and dip the glasses into the sugar. Allow them to set up for a minute or two.
5. Add some ice to each glass and pour the agua fresca over the ice. Garnish with a lemon wedge and sprig of tarragon.

Note: To make this into a refreshing cocktail, add ½ cup of vodka or light rum to the blender instead of ½ cup of water.
