add all the ingredients in a food processor, blender or bowl (use an immersion blender) and puree them until the consistency is fine.
Fill the fluid in your icecream maker and let it freeze. With this amount of fluid, your icecream maker should fit at least 1,5liters!
If you don´t own an icecream maker you can fill the mass in a freezer friendly bowl or box and let it freeze for at least 4 hours. Either stir it every 30 minutes or take the amount of granita you need out , let it stand for a couple of minutes and mix it in a blender or food processor. Let sit for another 1-2 minutes, until it´s creamy.
