Whisk the egg yolks, cream and sugar in a pot over low heat. Do not stop whisking and keep the heat low so that the custard doesn't curdle. (Don't worry if it does, there's an easy fix-see notes.)
Continue whisking until the mixture thickens and becomes a sauce. Add the brandy to your liking, from two teaspoonfuls to two tablespoonfuls (or more), but be careful not to add too much brandy or the sauce will become too runny. I used two tablespoonfuls.
Whisk well so that the sauce is completely smooth. Pour into a serving jug to pour over the Christmas pudding before it's cut into pieces, which makes for a beautiful presentation.
Alternatively, it may be more practical to cut slices of the Christmas pudding, and place in bowls, then pour the sauce over the top. I'd recommend this if you won't be finishing the entire pudding in one go.
Notes
If you did happen to get any lumps or curdled sauce, simply use an immersion blender, or small blender to make the sauce smooth (I won't tell!) I've never had it happen with custard, so if you follow my directions, you won't need the blender.
If you want to serve this to young children, remove some and add a drop of vanilla.
You can also use this sauce for other desserts, such as bread and butter pudding, topping ice cream, cakes or even pies.
