Begin by cutting the watermelon into manageable chunks, removing any seeds and rind clarity as desired. Use a sharp knife and a cutting board to ensure clean cuts.
Transfer the cut watermelon pieces into the blender. Add a splash of water if needed to facilitate blending, but keep it minimal to preserve the juice's natural thickness.
Blend on high speed until the mixture is smooth and slightly frothy, about 30-45 seconds. Look for an even, vibrant pink liquid with small pieces of pulp.
If desired, strain the watermelon juice through a fine sieve or strainer to remove pulp and seeds for a cleaner beverage. Use a spoon or spatula to gently press the liquid through.
Pour the freshly blended watermelon juice into glasses. Serve immediately for the freshest flavor and vibrant color, optionally garnished with a small watermelon wedge or mint leaf.
