Stay cool with this refreshing and delicious Watermelon Limeade courtesy of the Food Network.

Freeze 2 cups cubed watermelon until solid. Boil 3/4 cup each sugar and water, stirring to dissolve the sugar. Transfer to a pitcher and refrigerate until cold.

In a blender, puree 4 more cubes of watermelon and strain into the pitcher. Stir in 1 cup lime juice and 2 cups cold seltzer. Add the frozen watermelon (which doubles as ice cubes), some lime slices and enjoy.
