I bet this is good – and since I have an ice-cream maker, it would be easy work to make.
1 vanilla bean
550 ml (2 1/4 cups) thick cream (double cream)
550 ml (2 1/4 cups) milk
2 cinnamon sticks
6 egg yolks
100 g (1/2 cup) caster sugar
Split the vanilla bean down the middle and put it in a saucepan with the cream, milk and cinnamon sticks. Bring to the boil, remove immediately from the heat and leave to infuse for 1 hour.
Whisk the egg yolks and sugar in a large bowl until light and creamy. Pour the milk/cream mixture into the egg yolk mixture and whisk quickly to mix. Pour the custard into the saucepan and cook over very low heat (barely simmering) until it begins to thicken, stirring continuously with a wooden spoon. Do not let it boil! To test for thickness, dip the spoon into the custard, then draw a line on the back of the spoon. When the line stays and the custard does not run into it, it is ready.
Scrape the seeds out of the vanilla pod and mix into the custard. Strain the custard into a bowl, remove the vanilla pod and cinnamon stick and leave to cool.
To freeze, either churn in an ice-cream maker according to instructions, or pour into a freezer-proof bowl and freeze, whisking every 30 minutes, until the ice-cream is too stiff to stir. The whisking will give the ice cream a creamy texture. Once the ice cream is set, keep in the freezer until ready to serve.
