Neapolitan Lemon Granita
The granita can be frozen for up to 5 days. Stir before serving.
Mint or basil would be terrific additions to this recipe. Add 1/2 cup of herb leaves to the water and sugar and bring to a boil. Strain out the herbs once the syrup cools, and proceed with the recipe.
You can also freeze this mixture in an ice cream machine to make smooth, creamy lemon sorbet.
