Creating Lemon and Basil Granita is simple if you follow these steps:

1. Make the Syrup: In a small saucepan, combine the water and sugar. Heat over medium heat until the sugar dissolves completely, creating a simple syrup. Remove from heat and allow to cool.

2. Prepare the Basil: In a blender, combine the cooled simple syrup, fresh lemon juice, basil leaves, lemon zest, and salt. Blend until smooth.

3. Strain the Mixture: Using a fine-mesh sieve, strain the mixture into a shallow dish to remove the basil leaves and any solids.

4. Freeze: Place the dish in the freezer. After 30 minutes, use a fork to scrape the mixture; this will begin to create a flaky texture. Repeat this process every 30 minutes until the granita is fully frozen and fluffy, which should take about 2-3 hours.

5. Serve: Once the granita reaches the desired texture, serve it in chilled bowls or glasses. Use a fork to fluff the granita before serving to ensure it is light and airy.
