Sometimes simple is best. On a hot summer day I suggest grabbing some watermelon and lime and putting them through your juicer or blender.
For two glasses I used about half a medium sized watermelon and about two limes. Juice them or throw them in the blender. If you want less pulp you can put it through a strainer. It’s that simple! And so delicious. Bonus tip, use a glass straw, they are fun to use, easy to clean and good for the planet!
Other things you could add: mint, oranges, grapes, cucumber, the list is endless.
