Sandra’s Pro Tips

Here are a few of my favorite tips for making this easy recipe. Use these tips to help you make this sweet drink this summer.

  • I recommend using a high-powered blender like a Ninja or a Vitamix to make this refreshing drink.
  • If you don’t have a blender, you can use a food processor to make this drink.
  • I prefer to use a seedless watermelon so that you don’t have to worry about picking out the black seeds. However, blending the seeds with the ingredients is perfectly fine for you.
  • Making this into a slushy? Flash-freeze the watermelon on cookie sheets to help the icy texture or add ice cubes.
  • Turn this into a smoothie by leaving out the ice, you can even add some vanilla yogurt to make it creamy.

  1. oh yum! this would be great after a workout and i like how the color is so appealing. normally, healthy smoothies end up taking on a very ugly color but not this one… woohoo 😀

  2. So I was thinking I’d make the watermelon margarita… but I have no tequila. No fear! Instead, the Watermelon Cooler seems like it would be perfect spiked with what I do have- rum!
    I’ll let you know how it goes 😉
