- Freeze watermelon in a freezer bag for about 6 hours.
- Combine frozen watermelon and the rest of the ingredients.
- Process mixture in a blender of food processor until it is smooth; stopping once to scrape down the sides.
- Pour into glasses.
Blenders are for something other than Margaritas?
Very easy and refreshing idea. Great for kids. Looking forward to doing a batch with mangoes too as well as other fruit.
