Start by cutting the watermelon in half. Use a sharp knife to slice it into quarters, then cut the flesh into cubes. Make sure to remove any seeds if present.

Place the watermelon cubes into the blender. This will be the base of your juice, and blending will help extract all the delicious juice from the fruit.

Add the fresh lime juice and honey (if using) to the blender with the watermelon cubes. Lime juice adds a refreshing tang and balances the sweetness of the watermelon.

Pour in the cold water. This helps to thin out the juice and makes it easier to drink. You can adjust the amount of water based on your desired consistency.

Blend on high speed for about 30 seconds, or until the mixture is completely smooth. This ensures that all the watermelon is fully blended and juicy.

Place a fine mesh strainer or cheesecloth over a pitcher. Pour the blended watermelon mixture into the strainer. This step is optional, but straining will remove any pulp, resulting in a smoother juice.

Use a spatula or the back of a spoon to press down on the pulp, extracting as much juice as possible. Discard the pulp or save it for another use, like adding to smoothies.

Pour the freshly strained watermelon juice into glasses filled with ice cubes. This keeps the juice cold and refreshing.

Garnish with a slice of lime or a small wedge of watermelon on the rim of the glass for a decorative touch.

Serve immediately and enjoy the refreshing taste of summer!
