Using the measuring cups, put the required amount of fruit, lime juice, and sugar in the blender or food processor with a blade attachment. Blend these until the mixture is smooth.
Pour the purée into the metal pan. Ensure that the layer is not too thin as to stick to the floor of the pan or too thick as this would take longer.
Freeze for 30 minutes.
Remove the pan from the freezer at a point when the puree has started to freeze on the top and around the edges.
Scrape using the fork and return to freezer. After another 30 minutes, scrape again and return. Do this every 30 minutes for four hours until the puree is wholly frozen and looks dry and flaky. In case you have a topping such as lime zest and pepper flakes, stir them in a bowl and set aside
Now you can scoop your crunchy, melty granita in a bowl and serve to your six friends. Add the topping you set aside for extra goodness!
