Start by cutting a ripe watermelon in half and scooping out the flesh, ensuring to remove any seeds. Measure about 2 cups of the watermelon and place it into your high-speed blender. Gather the other ingredients.

With all your ingredients in the blender, secure the lid tightly. Blend on high speed for about 30-45 seconds, until everything is smooth and creamy. If you encounter difficulty with frozen pieces, use a tamper to help push the mixture down toward the blades.

Check the consistency of your Watermelon Smoothie—if you prefer a thinner drink, add a little water to the blender, starting with 1/4 cup. Blend again for another 10-15 seconds until fully incorporated.

Once your smoothie is perfectly blended, pour it into tall glasses or scoop it into a hollowed-out mini watermelon. Garnish with a slice of lime or a few fresh mint leaves.
