Make fresh Pineapple juice at home without a juicer. All you need is a blender and if you have the high-performance ones like the Blendtec one, you don't need to strain the juice at all!
Add all the ingredients to your blender and blend till no chunks of fruit remain and you have a smooth puree.
If you are using a Blendtec Blender, add all the ingredients in the order listed and select "Whole Juice" or blend on a Medium-High speed for 50-60 seconds.
Adjust water and sugar to the consistency you desire.
