Blend on high speed for about 30 seconds or until the mixture is completely smooth and velvety, with no large chunks visible. You should see a bright pink liquid with tiny seeds dispersed throughout.
Place a fine mesh sieve or strainer over a large bowl or jug. Pour the blended watermelon through the sieve to remove seeds and fibrous bits. Use a spatula or the back of a spoon to gently press and extract maximum juice.
Transfer the strained, bright pink watermelon juice into serving glasses. Chill in the refrigerator for at least 10 minutes to enhance refreshment. Serve cold, optionally garnished with a small watermelon wedge or mint sprig.
