Grind the vegetables until they are completely mashed up. Use a strainer to filter clear, pure juice. Adjust sugar and water at this stage to your preference. You can choose a thicker consistency by adding less water.
Experiment with other vegetables like celery or tomato. Try a salty version with lemon juice and salt. Don't discard the fiber; use it as a thickening agent for patties or blend until smooth and add milk for a smoothie.
Adjust the quantity of sugar according to the natural sweetness of the beets. Try adding other vegetables like celery, tomato, or coriander/parsley leaves for different flavors. If you wish not to discard the fiber, grind until smooth and add milk/water to make a smoothie.
