This is a sparkling drink built on unsweetened coconut water, with lime and lemon juice, a little sweetener and a pinch of sea salt. It takes 5 minutes, needs no cooking, and the recipe makes 2 servings. The card lists 30 calories and 3 grams of carbohydrates per serving.

The salt and the optional potassium chloride are what make it an electrolyte drink. The sweetener keeps it low carb, and the citrus keeps it from tasting flat.
What Goes in the Pitcher
The exact amounts are in the recipe card at the bottom.
- Unsweetened coconut water (1 cup): the base, with a light tropical flavor and no added sugar.
- Sparkling water (1 cup): adds fizz. Flavored sparkling water works too, as long as it is sugar-free.
- Fresh lime juice and fresh lemon juice (1 tablespoon each): brighten the drink. Fresh juice gives a livelier taste than bottled.
- Erythritol or another keto-friendly sweetener (1 tablespoon): sweetens without sugar. Stevia or monk fruit also work, so adjust to your own taste.
- Sea salt (1/4 teaspoon): the electrolyte part of the recipe.
- Potassium chloride (1/4 teaspoon, optional): for added electrolytes.
- Ice cubes and fresh mint (optional): to serve cold and to garnish.

Mixing It
Put the coconut water, sparkling water, lime juice, lemon juice, erythritol, sea salt and potassium chloride (if you are using it) in a large pitcher. Stir until the sweetener and salt have fully dissolved.
Fill glasses with ice, pour the drink over it and add mint if you like. Serve right away.
You only need a large pitcher, measuring cups and spoons, a spoon and glasses.
Ways to Change It
- Pineapple: add a splash of unsweetened pineapple juice for a more tropical taste. A small amount keeps it low carb.
- Grapefruit or orange: use grapefruit juice in place of the lime or lemon, or add a splash of orange juice.
- Berries: muddle a few raspberries or strawberries at the bottom of the glass before you pour.
What to Serve with It
Cheese crisps and veggie sticks such as cucumber or bell pepper go well with the drink. So does a light salad of mixed greens and avocado with a zesty vinaigrette. If you want more than one drink on the table, iced herbal tea or plain sparkling water fit the same theme.
