Remove the seeds from the vanilla pods and place the seeds and one pod in a saucepan. Add the milk, cream and sugar and heat until simmering. Remove the pod and discard.

To make the sauce place the water and sugar in a pan and heat until the sugar has dissolved, add in the strawberry jam and cook for a further minute. Add in 200g of the strawberries and stir.
Place into a blender and blitz until smooth. Pass through a sieve them stir in the remaining whole strawberries.
Remove the panna cotta from the fridge. Place the mould into a bowl of hot water being careful not to allow any water into the mould – this loosens the panna cotta making it easy to turn out onto a plate.
Once on the plate, drizzle over some of the strawberry sauce and top with the strawberries.
