Cut the vanilla pod lengthwise, scrape out the pulp and add the pod with the pulp to the milk. Add a few drops of sweetener and bring to the boil. Place the rice on a sieve and wash thoroughly under cold water.
Add rice to the boiling milk and let it swell at low heat for about 30 minutes. Stir in between. In the meantime wash, peel, quarter and core apples. Cut apple quarters into slices.
Put apples, apple juice, lemon juice and peel in a pot. Add a few drops of sweetener, bring to the boil and simmer for 4-5 minutes. Leave to cool a little. Flavour the finished rice pudding with sweetener again and layer in bowls with the stewed apples.
Drain the cranberries, pour over the rice pudding and decorate with apple wedges.
