Start by cutting your watermelon into small cubes. Removing the rind makes it easier for blending and ensures a smooth texture.

Squeeze the limes to extract about half a cup of juice.

In your blender, combine the diced watermelon, lime juice, honey (if using), and fresh mint leaves. Blend until completely smooth.

Using a fine mesh strainer or cheesecloth, strain the blended juice into a pitcher.

If the juice is too thick, add cold water until you reach your desired consistency.

Refrigerate the juice for about 30 minutes before serving.

Pour the chilled juice into serving glasses filled with ice.

Garnish with additional mint leaves or a slice of lime on the rim of the glass.
