This is a 100% sugar free drink (sweetened with naturally sweet stevia) that is perfect for summer. I love using frozen fruit as ice cubes in drinks, because they don't water the beverage down and are edible! I'm lucky enough to have a Meyer lemon tree at home, but of course you can use whatever lemons you have on hand.
- In a blender, puree the watermelon, lemon juice, lemon zest, salt and stevia until smooth.
- Pour into a pitcher and add water (adjust water for how liquidy the watermelon is). Taste and add stevia if desired.
- Chill, then pour into glasses (or mason jars!) and serve with frozen fruit ice cubes if desired.
