A quick and easy frozen watermelon margarita with a spicy Tajín rim that balances icy sweetness with a tangy chili-lime kick, perfect for summer refreshment.
Use ripe, juicy watermelon for best flavor. Chill watermelon and ice well for optimal slushiness. If blender struggles with ice, pulse ice first then add watermelon and liquids. Apply Tajín rim just before serving to keep it crunchy. For non-alcoholic version, omit tequila and add sparkling water or lemon-lime soda. Adjust sweetness and tartness to taste.
