Prep time: about 15 minutes
Standing time: about 1 hour
4 sweet apples
1 vanilla pod, split lengthwise
85 g (100 ml) sugar
The juice of 2 lemons
1 bottle semi-dry white wine
1-2 bottles mineral water (presumably fizzy)
Wash and peel the apples (keep the peel) and remove the center and seeds. Cut into thin sections. Put the apple sections, the peel and the vanilla pod in a punch bowl. Sprinkle the sugar over them and add the lemon juice. Pour in enough wine to just cover the apples, cover the bowl with a lid or cling film and refirgerate for about 1 hour.
Remove the apple peel and add the rest of the wine and ice-cold mineral water.
Replace the wine with apple juice and reduce the sugar.
