Panna Cotta

Pour the ProZero into a small saucepan.

Add the butter, sugar and cornflour.

If you are using a vanilla pod, cut it in half lengthwise and remove the tiny seeds from the inside with a sharp knife. Place the seeds and the cut vanilla pod into the small saucepan. If you are using vanilla essence instead, add this to the pan.

Place the pan over a gentle heat and stir well.

Keep stirring until the mixture starts to simmer and is thickened.

Take out the cut vanilla pod.

Pour the Panna Cotta mixture into a tall container or jug and use an electric hand-held blender to blend for 30-40 seconds.

Immediately pour the mixture into the ramekin dishes.

Leave to cool, then place into the fridge to set for 3-4 hours.
