Method

1. Heat the milk with the vanilla pod and allow to just come to the boil. In a large bowl, beat the eggs with the sugar.
2. Pour the hot milk over the egg yolks whisking vigorously. When completely mixed in, return to the pan.
3. Stir over a low heat until the mixture thickens sufficiently to coat the back of a spoon. This will take 5-6 minutes.
4. Drain into a bowl, remove vanilla pod (or add essence if using).
