What you will need

This recipe uses 5 simple ingredients that you can find at any grocery store:

  • 6 cups seedless watermelon cubed
  • 3 tbsp granulated sugar
  • 2 tbsp fresh lime juice
  • 1 pinch salt
  • 5 leaves fresh mint optional for serving

Step by step instructions

Step 1: Blend the Watermelon

Place the watermelon cubes in a blender and blend on high until completely smooth. Pour through a fine mesh strainer into a bowl pressing with a spoon to extract all the juice. Discard any pulp remaining in the strainer.

Step 2: Add Sugar and Lime

Whisk the sugar, lime juice, and salt into the watermelon juice until the sugar is fully dissolved. Taste and add a little more sugar if your watermelon is not very sweet. The mixture should taste slightly sweeter than you want the final granita to be.

Step 3: Begin Freezing

Pour the mixture into a wide shallow freezer safe baking dish. Place uncovered in the freezer. After 1 hour use a fork to scrape and stir the mixture, breaking up any frozen edges and pushing them toward the center.

Step 4: Scrape to Perfect Flakes

Continue scraping with a fork every 30 to 45 minutes for the next 2 to 3 hours until the entire pan is filled with light fluffy ice crystals. Serve immediately in chilled glasses or store covered in the freezer for up to 3 days, re-scraping before serving.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • fresh lime juice → fresh lemon juice works just as well and brightens the watermelon flavor beautifully
  • granulated sugar → honey dissolved in a little warm water for a more natural sweetener option

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Skipping the stirring and scraping steps which results in a solid block of ice instead of the fluffy crystal texture
  • Using a deep container instead of a wide shallow dish which slows freezing and makes scraping difficult
