I’ve been wanting to experiment with CAPI mixers for a while now and use it in all areas of the kitchen (not just in cocktails!) so I came up with this simple recipe for a seriously speedy granita. 

I used the delicious grapefruit sparkling soda in this super easy recipe, it already has a little sugar in it, so no need to melt in any extra. No cooking - just pour and stir, presto - granita!
