Soak gelatine in cold water. Bring cream, milk, gingerbread spice, 50 g sugar and vanilla sugar to the boil in a pot. Simmer briefly, remove from the heat and let it simmer for about 1 minute. Squeeze the gelatine and dissolve in the hot spiced cream.
Divide into four small moulds (each with a capacity of approx. 1/8 l) and leave to cool. Then chill for at least 4 hours, preferably overnight.
Stir starch and 2-3 tablespoons of juice until smooth. Boil up the rest of the juice and 1 tbsp. sugar. Stir in the starch and bring to the boil again briefly. Add frozen raspberries and defrost. Keep sauce warm.
Remove panna cotta from the edge with a sharp knife. Dip the moulds briefly in hot water. Turn out the panna cotta onto dessert plates. Arrange hot raspberries around it. Decorate with cinnamon stick and star anise.
Serve immediately.
