Hot summer? You need a refreshing cocktail! This sugar free and low carb watermelon-based drink can be made alcoholic or non-alcoholic, whichever you prefer. Watermelon isn't super low in carbs, so plan to only have one of these drinks as a special treat. Here's my video to show you how easy it is to make - you're going to love it!
Can't see the video? Watch it on YouTube!And although you might not eat watermelon on a regular basis, it's good to know that it's a good source of vitamin A, B6 and C, lots of lycopene, antioxidants and amino acids.
How to Make a Low Carb Watermelon Cocktail
Dice up some fresh watermelon, removing any large seeds that you see. Add it to a blender with lime juice, white rum (if using) and low carb sweetener of your choice - I prefer a liquid sweetener for this recipe, something like a few drops of liquid Stevia or a tablespoon of homemade low carb simple syrup would be perfect. Or you might not need it at all, depending on your preference.
Blend until smooth, then strain the mixture through a sieve into two glasses to remove the pulp. I'm afraid you'll have to do this stage otherwise the cocktail will have an odd texture.
Next, add some ice cubes to each glass.
Then top up with club soda or seltzer water.
Garnish with a mint sprig, if you like!
This is such a gorgeously refreshing drink that is perfect for the summer! You might like to check out all my other low carb drinks - especially my new recipe for a Keto Mai Tai!

I made a watermelon kombucha with a scoop of watermelon electrolytes. Yum. You could also add the electrolytes to 1 oz. of tequila, seltzer and ice if you want it to be alcoholic.
