if you've never had one, granitas originally come from Sicily, but over the years they've worked their way up The Boot and all over Italy.
They're usually made up of fruit, water/juice and sugar. It's what's known as an Italian ice, but the true Sicilian granita always has a much grainier or coarser texture.
Take your pineapples' hat off.
Cut it in half lengthwise.
Take the core out and cut out pieces of meat.
Put the pineapple in a food processor or blender.
Grind it into a puree, add the sugar as this keeps it from freezing into a solid block of ice, and pour it into a 13 x 12 baking dish.
Put the whole thing into your freezer.
Rake it with a fork every 30 minutes or so to break it into icy crystals. Do this until it's the texture you want, to scoop it into serving dishes.
Serve it up!
