Wash everything well. Rinse the cucumber, apples, and mint.
If your produce isn’t organic, consider peeling the cucumber.
Prep the produce. Core the apples and cut them into chunks. Slice the cucumber into large pieces. Remove lemon peel if using a juicer.
If using a juicer: Juice cucumber, apples, mint, and lemon in that order.
Stir the juice, then taste and adjust with a pinch of sea salt if desired.
If using a blender: Add cucumber, apples, mint, lemon juice, and 1 cup cold water. Blend on high until smooth. Strain through a fine mesh sieve or nut milk bag for a lighter texture, or keep it pulpy for extra fiber.
Add more water to reach your preferred consistency.
Chill and serve. Pour over ice for extra refreshment. Drink immediately for the brightest flavor and most nutrients.
