Step 1: cut the watermelon into cubes. Be sure you are using a seedless watermelon. Add the watermelon to a blender. If you have a small blender, you may have to work in batches and only process half of the watermelon at a time.

Step 2: Add in the water, sugar, and lime juice. You can omit the sugar or add less if you’d like.

Step 3: Place the lid on the blender and blend until completely pureed. You can strain the watermelon water before drinking, but I prefer it as is.

Step 4: Pour the watermelon juice into a glass filed with ice and garnish with a lime wedge. Be sure to serve the drink very cold.
