Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Egg yolks
Thicken the custard as they set when gently heated, giving it a smooth, rich body.
Chocolate
Provides the chocolate flavour and dark colour of the custard.
Cream
Adds fat for a rich, smooth texture and a silky mouthfeel.
Milk
Forms the liquid base of the custard, diluting the richness of the cream.
Sugar
Sweetens the custard and balances the bitterness of the chocolate.

The step that matters

Add beaten egg yolks and stir until thickened. Egg yolks set when heated, but if the mixture gets too hot or is not stirred, they can curdle into lumps. Stir steadily over gentle heat to keep the custard smooth.
