So refreshing! My dad made these for us once years ago. When I realized I had both strawberries and watermelon in the kitchen, I tried to remember what he did. After I was finished, I recalled that he tossed in a few ice cubes to help the blender along, but I didn’t do that today.
(When you have fruit this way — so concentrated — its doubly important that you use organically grown.)
1 quart strawberries
1/2 small seedless watermelon
1 T. sugar (optional)
Top the strawberries and rinse lightly. Place on a cookie sheet and freeze for at least 2 hours.
Remove from freezer and let thaw slightly as you cut the watermelon in chunks. Put both in blender and pulse until a smooth slush. Taste and sweeten with more sugar, if desired.
