Fresh watermelon juice is a super refreshing drink for the summertime. You have to try to make it this summer. Start by cutting up cubes of fresh watermelon and trim off any white parts near the rind. Remember to keep out all the seeds. Next, fill up a blender almost to the top and blend starting low, then increasing blender speed to high. Once it's fully blended, turn it off and add more watermelon chunks. Repeat the blending process and blend until smooth. An option is to strain if you want the juice to be without foam and fibers by keep it all natural and pour it straight into the glass. Add some ice if you want to make it colder. I hope you give it a try and enjoy.
