Watermelon Vodka Granita

...Or what to do with a massive watermelon in the fridge when you're sick of eating watermelon.

It's yummy and light and the prettiest pink. First, make the sugar syrup, which only takes a couple of minutes. For half a watermelon, I used half a cup of sugar and half a cup of water. Melt the sugar in a saucepan with the water then let the sugar syrup cool. Cut the flesh of half a watermelon into big cubes. Puree with a stick blender and stir through the cooled sugar syrup and as much vodka as you like (half a cup for a mellow hit). Freeze for two hours then buzz it with the stick blender to break up the ice crystals. Do this once every hour until you have a smooth sorbet, or leave it to freeze completely and breark it up with a fork for a snowy granita.
