Put gelatine leaves in a bowl of cold water. Leave them for 5 minutes to soften.
Step 2: Heat the cream
In a saucepan, add cream, milk, and sugar. Slice the vanilla pod and scrape the seeds in. Add both seeds and pod. Heat gently until sugar dissolves. Do not boil.
Step 3: Add gelatine
Take the pan off the heat. Remove the vanilla pod. Squeeze water from gelatine leaves and stir them into the warm cream. Mix until fully melted.
Step 4: Pour into moulds
Pour the mix into glasses or ramekins. Let them cool a little. Cover and put in the fridge for at least 4 hours, or overnight, until set.
Step 5: Serve
To unmould, dip the ramekin base in warm water for a few seconds. Turn onto a plate. Serve plain or with fruit sauce.
Notes
Do not boil the cream. Keep it gentle.
If using powdered gelatine, dissolve it in 2 tbsp hot water first.
