How to Make Purple Drink Without Food Dyes
To make this electrolyte drink purple I used butterfly pea tea flowers combined with lemon juice. Naturally blue butterfly pea tea will turn purple once mixed with acidic ingredients such as lemon juice. The longer you steep the flowers in water, the more vibrant the layer will become. Butterfly pea tea tastes neutral so it will taste like lemonade!
You can skip the butterfly pea tea flowers as they are only used for color. You can also substitute them with hibiscus flowers which will make the liquid pink and then the slurpee will turn red once combined with lemon juice. Unlike butterfly pea tea, hibiscus flowers will add some flavor and make the slurpee slightly more sour/acidic.

How to Make One Serving at a Time
This recipe makes 6 servings so it's unlikely you'll need to make the whole batch at once. Instead, you'll likely need just one to two servings.
To make a serving, blend 1/3 cup (80 ml/ fl oz) of the purple liquid with 2/3 cup (160 g/ 5.6 oz) ice, or as much as needed for snow-like consistency. If the slurpee is too icy, add a dash of water. If it's too runny, add more ice.
You can make a quick electrolyte drink instead of a slurpee by mixing 1/3 cup (80 ml/ fl oz) of the purple liquid with 2/3 cup or more of still or sparkling water.
Top Tips For Making Electrolyte Drink at Home
Here are tips for making sugar-free electrolyte drink at home.
- Drink with/after meals (not on an empty stomach). Start with a cup per day and increase to no more than 2 cups per day to avoid stomach discomfort. Too much magnesium citrate causes loose stools so keep that in mind. One cup will provide about 50% of your daily magnesium and two cups will cover your daily needs.
- Instead of potassium chloride, you can use lite salt or cream of tartar. To read more about potassium supplements, check out this post: The Importance of Potassium in Low-Carb Diets.
- Instead of Allulose, you can use other healthy low-carb sweeteners from this list. Stevia (in the form of drops) is a good option if you are following a low FODMAP diet. If you don't like sweeteners, they can be omitted altogether.
- Make electrolyte drinks and drink them every day, especially if intermittent fasting is part of your lifestyle.

Ingredients (makes 6 servings)
Instructions
- Place 8 to 12 butterfly pea tea flowers into a jar filled with 1 1/2 cups of cold water. Let it steep at room temperature for at least 30 minutes or in the fridge for up to 8 hours. The longer you leave it the deeper the color. Remove and discard the flowers.
- Meanwhile, juice the lemons.
- Mix the blue tea with lemon juice to turn it purple. Add sweetener (Allulose or Erythritol) and stir until fully dissolved. Add magnesium, potassium, and salt.
- Place the purple liquid in a blender together with ice cubes.
Note: For better magnesium absorption, mix the Calm with a small amount of water and let it sit for a few minutes before adding to the blender. Your magnesium is ready when any fizzing has settled and the water is no longer cloudy.
- Blend until you get snow-like consistency.
- Serve immediately. You can make one or two servings at a time and keep the remaining purple liquid in the fridge until ready to make the slurpee.
Note: See recipe tips for the amounts needed to make 1 serving at a time.
