Prepare the ingredients: Wash the red cabbage thoroughly to remove dirt and pesticides. Peel and chop the ginger and apple, and cut the lemon in half, removing any seeds.
Blend: Add the red cabbage, ginger, apple, and lemon into a high-speed blender. Add 1 cup of water or coconut water to help blend the ingredients smoothly.
Strain (Optional): If you prefer a smoother juice without pulp, strain the mixture using a fine mesh strainer or cheesecloth. Serve: Pour the juice into a glass, serve chilled, or add ice for a refreshing touch.
