I admit it, this is not truly a granita. I'd like to think it's the easier, faster way of making a granita-esque treat.
I definitely eyeballed this recipe so adjust the proportions to your liking.
Sparkling Lemonade "Granita"
1/4 Cup Coconut Millk
Juice from 1 Lemon
Zest from 1 Lemon
5 Ice Cubes
3-5 Drops of Stevia
Blend the above ingredients together in a blender or Vitamix.
Use a spoon to ladel the "granita" into fancy ice cream glasses and top with a splash of Lemon flavored sparkling water. Enjoy!
