Frozen Oranges - cooking recipe

Ingredients

6 oranges
1 liter vanilla ice cream (the best you are prepared to buy)
150 ml orange juice concentrate
3 tablespoons Grand Marnier (or other orange flavoured liqueur)

Preparation

Remove a\"lid\" from the top of each orange (retain the lid).
Carefully remove all the pulp from the orange-I use a dessertspoon to do this.
Allow the ice-cream to soften for a minute or two, then working quickly, stir through the liqueur and concentrate and fill the orange shells with this mix.
Replace the lids.
Freeze for at least 6 hours but preferably overnight.
Remove from the freezer about 10 minutes before serving so they go frosty.
These look good with a sprig of orange or lemon leaves poked into the top before serving*note-don't be tempted to use the pulp in place of the concentrate, the flavour is all wrong.
Use the pulp for juicing or something.
