A simple, insanely refreshing Caribbean rum punch slushie perfect for backyard gatherings, blending tropical flavors with a smooth, icy texture.
Use freshly squeezed lime juice for best flavor; bottled lime juice can taste bitter. Adjust sweetness carefully by starting with less simple syrup. Pulse blending to avoid watery texture. Chill glassware before serving to keep slushie cold longer. Grenadine adds color and fruity depth. For non-alcoholic version, omit rum and add sparkling water or ginger ale. Blend in batches for large quantities to avoid overloading blender.
