A refreshing summer cocktail made from fresh watermelon and blueberries.
Puree the watermelon in a blender and strain into a glass. Use a spatula to stir if it doesn't go through too well.
Combine the lime juice, simple syrup, blueberries, and mint leaves in a pitcher and muddle.
Add the watermelon juice, then the tequila. Stir and chill.
