Peel and core the ripe papaya. Cut the pulp into pieces and place in a tall container. Add the xylitol and vanilla and puree with the blender. This can of course also be done in a mixer. Add the yoghurt and mix well again. Chill in the refrigerator for about 30 minutes.
If the papaya has been stored in the refrigerator, the dessert is ready to eat. You can use a small papaya or about a quarter of a giant papaya. In my experience, the big ones are more aromatic.
