Combined with coconut water, which delivers natural electrolytes and hydration, this slushie recipe stands out for both flavor and nutrition.

  • Low calorie: Only 77 calories per serving.
  • No added sugars: All sweetness comes from fruit.
  • Hydrating: Coconut water offers potassium and electrolytes.
  • High fiber: 3 grams per serving.

Expert Tips for Success

  • Freeze thoroughly: Uneven freezing leads to a watery slushie. Spread fruit out for quick, even freezing.
  • Blend last-minute: To preserve texture, make slushies just before serving.
  • Adjust acidity: More lime juice boosts tartness and freshness.
  • Experiment with herbs: Try basil or mint instead of lemongrass for variation.

Variations: Make It Yours

This recipe is endlessly customizable. If star fruit isn’t available, substitute with other tropical fruits like mango, pineapple, or papaya. You can swap lemongrass for fresh mint or basil for a different herbal twist. For sweetness, add a splash of agave or maple syrup, though natural fruit sugars usually suffice.

  • Mango Coconut Slushie: Substitute star fruit with frozen mango.
  • Pineapple-Basil Slushie: Use pineapple and basil in place of star fruit and lemongrass.
  • Add a spicy kick: Incorporate a small amount of grated ginger.
  • For a cocktail: Add tequila or vodka for an adult beverage.
