What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Use a very ripe banana with brown spots to naturally sweeten the smoothie without added sugar.
- 2Segment the grapefruit over a bowl to catch the juice, then add that juice to the blender for extra citrus flavor.
- 3Blend the spinach and coconut water first to break down the leaves completely before adding fruit.
- 4Chill the coconut water beforehand so the smoothie stays cold without needing extra ice.
- 5If you prefer a thicker texture, freeze the banana in chunks before blending.
- 6Taste before serving and adjust sweetness by adding more banana or a splash of orange juice.
