To make panna cotta, you'll need:
50cl or 2 cups whole cream
40g or 3 Tbsp sugar
2 gelatin sheets
1 vanilla bean or 2 packets of vanilla sugar or 1 teaspoon of vanilla extract
To make Panna Cotta, heat the cream with the vanilla and sugar until boiling.
If you're using a vanilla bean, you can leave the mixture to cool to allow the vanilla flavor to completely infuse into the cream, then re-heat the cream to dissolve the gelatin.
Remove from heat and immediately melt the softened gelatin sheets into the hot cream.
Pour into ramekins.
Let cool for 30 minutes at room temperature, then chill the glasses in the fridge for at least two hours before serving.
