Bring milk and cream mixture to boil and then simmer it. Add sugar and stir well.

In a bowl, beat the egg yolks well and add cornflour and vanilla essence to this. Whisk well till it is mixed thoroughly. (you'l get a light yellow color at this stage)

To this egg yolk mixture add some of the hot milk-cream mixture and whisk well as you add in.

Now incorporate the mixture from step3 into the rest of the milk-cream mixture. (It is very important to stir as you do this). Check for the sweetness and add more sugar if required!!

Let it cook for about a minute or two on the low flame and keep stirring. Transfer it into a serving dish and allow it to cool.

For a very simple chocolate sauce, double boil dark chocolate (i used Nestle's dark chocolate) and butter together.

Mix one teaspoon of milk to this to get a smooth consistency. Add in some chopped nuts to this and serve it along with the custard.
