8 egg yolks
75g caster sugar
300ml milk
300ml double cream
1 vanilla pod, split
Beat the egg yolks and sugar together in a
bowl until well blended
Place milk and cream together in a
non-reactive pan, add the split vanilla pod scraping out the seeds, and
bring to a low boil
Pour a little of the hot milk/cream over
the egg yolks, mix well then pour this mixture back into the milk pan.
Return to the heat and stir with a whisk until the sauce has thickened. DO
NOT BOIL or you will end up with a pan of scrambled eggs.
Keep stirring until sauce is thick enough
to coat the back of a spoon.
