Keto black magic lemonade for Halloween. Fresh lemon, monk fruit sweetener, and a tiny bit of food grade activated charcoal. Bright, clean taste with a bold black color. Easy to mix for a party pitcher or one glass.
1 cup fresh lemon juice, strained (about 6–8 lemons)
5 cups cold water
½ to ¾ cup monk fruit sweetener (to taste)
¼ to ½ teaspoon food grade activated charcoal powder (start small)
1 cup ice, plus more for serving
Pinch sea salt (optional)
½ teaspoon vanilla extract (optional)
Garnish: thin lemon wheels, fresh mint, or blackberries
Warm ½ cup of the water. Whisk in the monk fruit until it looks clear.
In a large pitcher, mix lemon juice, the rest of the cold water, the sweetener mix, and a small pinch of salt. Stir well and taste.
Sprinkle in ¼ teaspoon activated charcoal. Whisk for 30 seconds until smooth. For a darker look, add a tiny bit more.
Stir in the ice and the vanilla if using.
Chill for 20–30 minutes. Stir again before you pour.
Serve over fresh ice and add a lemon wheel or mint.
Use food grade activated charcoal only. Charcoal may affect some medicines. If unsure, skip the charcoal.
Add charcoal in small pinches. Too much can make the drink feel chalky.
Monk fruit blends vary in sweetness. Start low and adjust.
For sparkle, swap 1 cup water with unsweetened sparkling water right before serving.
Strain lemon juice for a clean, smooth look in the glass.
