Ingredients
- 4 cups, cubed and chilled seedless watermelon
- 1/2 cup granulated sugar
- 1/2 cup water
- 1/4 cup, freshly squeezed lime juice
- 1 tsp, finely grated lime zest
- for garnish (optional) fresh mint leaves
Instructions
- Step 1: In a small saucepan, combine 1/2 cup granulated sugar and 1/2 cup water. Heat over medium heat, stirring occasionally, until sugar dissolves completely, about 3-4 minutes. Remove from heat and let cool.
- Step 2: In a blender, puree 4 cups chilled seedless watermelon cubes until smooth. Add the cooled sugar syrup, 1/4 cup freshly squeezed lime juice, and 1 tsp finely grated lime zest. Blend briefly to combine.
- Step 3: Pour the mixture into a shallow metal or glass baking dish and place in the freezer. Every 30 minutes, use a fork to scrape and break up the ice crystals, repeating this scraping process 3-4 times until the granita is fully frozen and fluffy.
- Step 4: Serve granita in chilled bowls or glasses garnished with fresh mint leaves if desired.
