A quick and easy frozen watermelon margarita slushie with a tangy, spicy Tajin rim, perfect for cooling off on hot summer days and impressing guests with minimal effort.
For best flavor, serve immediately as the slushie melts quickly. Freeze watermelon cubes beforehand for a thicker texture and reduce ice needed. Adjust sweetness and tartness to taste. Use quality blanco tequila for best results. Rim glasses carefully with lime juice and Tajin-salt mixture to avoid clumps. Non-alcoholic version can be made by substituting tequila and triple sec with sparkling water or lemon-lime soda and adjusting lime juice and simple syrup accordingly.
