Watermelon Drink

I bought my first watermelon for this summer and decided to do something different.  This is a very refreshing drink.  Should you like an alcoholic version you can add some vodka.

4 cups chopped seedless watermelon (about 1 kg)

1/4 cup freshly squeezed lemon juice

1 tablespoons sugar

1/4 cup vodka. (optional)

Method

1. Working in batches, puree in blender watermelon with lime juice and sugar until smooth. 
   
   
2. Transfer puree to a pitcher; add vodka, if desired. Cover, chill until ready to serve.
   
   
3. Stir, pour into tumblers, over ice. Garnish with mint.
