I made some watermelen ice milk last week that was delicious~!
put a half a watermelon in the blender until smooth(remove seeds)
add about a cup of milk or half and half and about a half cup of sugar (TASTE TEST FOR BEST RESULTS)
put it in the ice cream maker and enjoy
I just love it cold and sweet.
I don't eat near as much as I would like because of all the natural sugar in it.
