Start by soaking gelatin sheets. Put them in a bowl and cover with cold water and a couple of ice cubes.
In a pot warm whipping cream, milk and sugar just until warm.
Scrape the seeds from the vanilla pod and add them to the pot. Stir well.
Once gelatin sheets have softened, squeeze then gently with your hands to remove excess water, then add to the warm cream mix. Stir well and let cool.
Pour the flavored cream (panna cotta) to silicone molds or dessert glasses. Place in the fridge to set for at least 6 hours or better yet overnight.
