Use very ripe watermelon for the sweetest flavor. Freeze the watermelon cubes in a single layer so they blend easily later. If the slushie is too thick, add a splash of water and blend again. If it’s too thin, add more frozen watermelon. This drink is best served immediately while icy and fresh, but leftovers can be frozen and re-blended or turned into popsicles.
