I've been on a watermelon kick lately and I've tried it lots of different ways. This is one of my favorites.

Ingredients Nutrition


  1. In a blender put the seltzer.
  2. Squeeze the juice from half a lemon on top of the seltzer. Add the splenda and then the watermelon.
  3. Blend until slushy.
  4. Depending on your blender, you may need a tad more seltzer.

completely forgot to add my review when I tried this last OCT...made this one twice, once as written...making it as written, everyone was unimpressed...the 2nd time I adapted the recipe & went the orange route instead of lemon and arrived at a result EVERYONE liked...the flavors just melded better...the recipe is SIMPLE enough & I suppose some might find it a DECENT enough concoction, but we found it LESS than spectacular and we wont be adding it into our ARSENAL come summertime...but thanks for sharing!

Have now made this twice with variations and enjoyed both immensely. The first time I did not pay attention to the ingredients list carefully and made the slushy with diet 7Up. Because the soda included sweetner, the Splenda was omitted. The second time I made it with seltzer as directed and used just 1 tablespoon of sweetner as that was sufficient for my tastes. Both drinks were light and refreshing, but i did like the seltzer version a bit more because the watermelon was a bit sharper. Either way, it was a crisp taste of summer in a glass. Thanks.

WOW! This was really different and tasty! It took forever for my cuisineart blender to handle it though! LOL My teen son didn't care for it. I guess it was too "natural" tasting than sonic's! But I absolutely will be making it for myself again! Thanks for the post!
