Start by submerging the gelatine in cool water to soak.
In a saucepan, heat the milk and cream, then add the vanilla and sugar. Do not boil the milk. You only need enough heat to dissolve the gelatine.
Remove the gelatine from the water and squeeze out the access water.
Add the gelatine and stir to dissolve.
Pour the Panna cotta mixture into the Panna cotta moulds and leave to cool down.
Cover and refrigerate overnight.
To remove the panna cotta simply dip the mould into warm water and turn it over on a plate. A little shaking might be needed.
Serve with berry coulis and fresh berries.
