Super simple low carb watermelonade is made with fresh watermelon, water and this lemonade electrolyte powder.
- Fresh Watermelon: cubed and pureed in a blender.

Steps by step instructions
How to make the low carb watermelonade?
STEP 1: Cube and puree the watermelon in a blender. Pour through a fine mesh sieve and discard any solids.
STEP 2: pour the blended watermelon into a pitcher and then add the water and lemonade electrolyte powder. Mix with a long spoon to ensure you are able to stir from the bottom.
STEP 3: Pour over ice and enjoy.
Optional: garnish with a few berries like blueberries or blackberries and a lemon wedge.

Substitutions
If you simply want the lemon flavor without the electrolytes you can add a ¼ cup of freshly squeezed lemon juice. However, adding lemon juice will also increase the number of carbs in this drink. Sweeten with your preferred low carb sugar substitute.
