Ingredients Method Notes

Ingredients
  

Watermelon
  • 4 cup fresh watermelon, cubed and frozen overnight Use cubed watermelon frozen overnight for the slushy texture.
Pineapple
  • 0.5 cup frozen pineapple chunks Frozen pineapple brightens the watermelon flavor without making it taste strictly pineapple.
Lime and sweetener
  • 0.25 cup fresh lime juice
  • 2 tbsp agave syrup
Coconut water and salt
  • 0.25 cup coconut water Use coconut water instead of plain water for natural sweetness and electrolytes.
  • 1 pinch of salt
Optional turmeric version
  • 0.25 tsp turmeric Optional golden anti-inflammatory version; add along with the other blend-ins.
Garnish
  • 1 pineapple leaf
  • 1 lime wedge

Method
 

Freeze the fruit
  1. Freeze the cubed watermelon and the frozen pineapple overnight so you have firm pieces for a slushy blend.
Blend into a slushie
  1. Add the frozen watermelon, frozen pineapple, lime juice, agave syrup, coconut water, and salt to a blender and blend until smooth and slushy, scraping down once if needed.
  2. If using the turmeric version, blend it in with the other ingredients until the color is evenly golden and the texture stays slushy.
Serve
  1. Pour the slushie into chilled glasses so it stays thick and cold.
  2. Garnish each glass with a pineapple leaf and a lime wedge, then serve immediately.

Notes

Pro tip: blend briefly, then stop—over-blending warms the mixture and can make it less slushy. Store any leftovers in the freezer for up to 1 day; re-blend with 1–2 tbsp coconut water if it hardens. Freezing longer can reduce texture. If you want it dairy-free and vegan, this recipe already is as written; for a no-added-sweetener swap, use only extra lime juice and slightly more agave alternative to taste (start with 1 tbsp).
