• Step 1
  Combine the zest and sugar with your fingers, until the sugar is yellow and aromatic.
• Step 2
  In a medium saucepan, combine 1⁄2 cup of the water with the zested sugar, and heat over medium heat until the sugar is completely dissolved.
• Step 3
  Remove from heat and stir in the remaining water, then chill in refrigerator.
• Step 4
  Combine all ingredients in a food processor or blender, and purée until leaves are well chopped. Allow mixture to sit for 1 hour, refrigerated.
• Step 5
  Pour into a covered container and place in the freezer for 1 hour. Remove from freezer, and stir the frozen crystals into the center of the container with a fork. Return the container to the freezer, and repeat the process every 30 to 45 minutes, stirring carefully each time, until you have a fully frozen container of crystallized granita.
