Start by cutting the clementines in half. You can either use a juicer or scoop out the flesh. I prefer using an electric juicer because it gets all the flesh out, leaving a perfect clementine bowl to scoop the sorbet into. Don't throw the skins away!
Add 250 ml of orange juice to give you 500 ml of juice.
Take the juice and heat gently in a small pan along with the honey. Stir until all the honey is dissolved.
Next, we are going to add the orange liqueur and stir well. Then we want to chill it completely in the fridge.
Pour the juice into a shallow metal tin and freeze until firm. Then, rake over with a fork to get the crystals. Repeat this several times until the juice is all mixed up and frozen.
Lastly, spoon the sorbet into the reserved clementine shells and refreeze till required. Zest a bit of citrus on top and serve right away!
