Lemon & Lime Crush - cooking recipe

Ingredients

6 lemons

Preparation

Zest 2 of the lemons and 2 of the limes.
Juice all the fruits and keep the empty shells to serve the granita.
Tip the juice, zest, lemongrass, lime leaf (if using), and sugar into a bowl.
Pour over 2 cups boiling water.
Stir everything together until the sugar has dissolved, then leave to cool and infuse.
Strain the lemon syrup into a tray and freeze, mixing every couple of hours to break up the ice crystals.
