This recipe serves 3 people.
Optional step: rim your glasses with coconut. Place some coconut on a shallow plate, then run a wedge of lime along your glass where you'd like your rim to be. Press the moistened rim into the coconut and shake off excess.
Add rum, sweetener, pineapple juice, coconut water, cream of coconut and lime juice to your pitcher. Stir well to combine. Or add all ingredients to blender and blend well. Taste. If you prefer a little more tang, add some more lime juice. If you prefer more sweet, add more sweetener to taste. When it's just how you like it, serve over ice and garnish if you wish.
