Ingredients
1/2 cup white sugar
1/2 cup water
4 cups cubed watermelon
3 cups cold water
1/2 cup fresh lemon juice
6 cups ice cubes
Instructions
Place the watermelon into a blender. Cover, and puree until smooth. Strain through a fine mesh sieve.
Bring sugar and 1/2 cup water to a boil in a saucepan over medium-high heat until the sugar dissolves, about five minutes. Remove from heat. Stir in 3 cups of cold water and the lemon juice. Divide the ice into 12 glasses, scoop 2 to 3 tablespoons of watermelon puree over the ice, and then top with the lemonade. Gently stir before serving.
