Wash and prep: Rinse kale, apples, cucumber, and mint. Trim tough kale stems, core apples if you like, and peel the lemon and ginger.
If using a juicer: Feed kale, cucumber, apples, ginger, lemon, and mint through the juicer.
Stir the juice to combine flavors.
If using a blender: Add chopped ingredients to the blender with 1/2–1 cup water or coconut water. Blend until very smooth.
Strain (blender method): Pour the mixture through a fine mesh sieve or nut milk bag into a bowl, pressing to extract the juice.
Taste and adjust: Add more lemon for brightness, apple for sweetness, or ginger for heat. If it’s too strong, dilute with a splash of water.
Serve cold: Pour over ice or chill for 10 minutes.
Drink fresh for the best flavor and nutrients.
