There's a mistake on the recipe...

When you make the custard, you should always pour the milk into the whisked egg, not the other way round.

This is because the heat of the milk in the pan will cause the egg to curdle.

You should pour the milk gradually into the egg, whisking constantly. Let the milk dribble down the side of the bowl so it cools down a bit.

Then return the mixture to the pan and heat again to thicken.
