Watermelon & Lime Granita
Ingredients (Serves 6-8):
2lb 4oz watermelon flesh, chopped
A generous pinch of salt
2 tbsp finely grated lime zest
Juice of 2 limes
3½ oz caster sugar
Process the watermelon flesh in a blender with the salt, lime zest and juice, then pass it through a fine sieve into a freezer-proof stainless steel container or plastic tub.
Use the back of a ladle to push through and strain out any remnants of watermelon pips. Stir in the sugar, and continue stirring until it is dissolved.
Place the container in the freezer to chill, stirring with a fork every hour or so, paying special attention to the sides of the container where the mix will freeze solidly if unattended.
To serve, fork through the mixture to get crystals and spoon into chilled bowls or glasses.
