One of the simplest ways to do this is by blending blue kale with your favorite fruits and other greens. Start with small amounts – about 1-2 cups of fresh leaves per serving – as the flavor can be overpowering if not balanced correctly.
For example, combine blue kale with frozen berries, banana, and a squeeze of lemon juice for a delicious and refreshing breakfast smoothie. You can also blend it with other leafy greens like spinach or collard greens to create a nutrient-packed green smoothie. When juicing, use the leaves only – the stalks are too fibrous – and combine them with citrus fruits like oranges or grapefruits.
To minimize any bitterness from the blue kale, be sure to add plenty of sweetness through your choice of fruits. Experiment with different combinations to find a flavor you enjoy. A good rule of thumb is to start with 10-20% of the total serving as blue kale and adjust to taste.
