Soak the gelatine in cold water. Put the whipped cream and sugar in a saucepan. Slit the vanilla bean and scrape out the seeds. Add the vanilla pulp and pod to the whipped cream. Cook for 15 minutes. Take out the vanilla pod. Add gelatine to the whipped cream and let it melt. Form into ramekins and set in the refrigerator for one night.
Mix the strawberries with the powdered sugar and strawberry liqueur or raspberry brandy and crush. Turn out the panna cotta and serve with the strawberry sauce.
Tip: Local strawberries taste best!
