You would be hard-pressed to find something more refreshing than watermelon. This cooler is easy to make, beautiful to behold, and not too sweet. You'll want a pitcher of it in the refrigerator all summer.
Ingredients

* 1/4 cup sugar, divided
* 4 teaspoon fresh lemon juice, divided
* 16 cups ice cubes, divided
Garnish:
* lemon slices; mint sprigs
Directions
Cut watermelon flesh into 2-inch chunks and discard rind. Pur?e one fourth of watermelon in a blender with 1 Tbsp sugar, 1 tsp lemon juice, 4 cups ice, and a pinch of salt.
