Jun 6, How does a watermelon and kale juice sound? It's a surprisingly sweet and refreshing combination, especially during the heat of summer. Run the watermelon and cucumber pieces through a juicer following manufacturer's instructions, and place juice into a pitcher. Stir in lime juice, and serve. Wash watermelon and beets. Peel the beets and remove the hard watermelon skin before juicing them. Taste and add some freshly squeezed lemon juice (optional). Garnish with mint and watermelon wedge (optional). Drink right away or store in a sealed jar in your fridge. Sep 20, Watermelon is one of the most nutritious foods with fat-burning and heart-healthy compounds. Here is my favorite watermelon juice recipe.
