Cut the vanilla pod in half lengthways and scrape out the seeds with the back of a knife.
Place the cream, vanilla pulp and scraped-out pod in a pan. Add the sugar and bring to the boil. Simmer over a low heat for 5 minutes. Then pour the cream through a fine sieve into a bowl.
Remove the gelatine from the water, squeeze out well and dissolve in the hot vanilla cream. Leave the mixture to cool and pour into cold rinsed pudding molds or glasses.
Place the ramekins in the fridge for at least 4 hours and leave to set.
Before serving, dip the pudding moulds briefly in lukewarm water. This helps to release the panna cotta from the mold. Now turn the panna cotta out onto plates.
Prepare the fruit sauce
Finely puree the frozen fruit with a little water in a blender and pour over the panna cotta.
