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

What each ingredient does

Chocolate
Melts into the milk to give the sauce its deep flavour and body.
Egg yolks
Proteins set on gentle heating, thickening the sauce into a smooth, honey-like texture.
Sugar
Dissolves into the liquid to add sweetness and balance the bitterness of the chocolate.
Milk
Forms the liquid base that the chocolate melts into and carries the other ingredients.
Cream
Adds fat for richness and a silky mouthfeel.

The step that matters

Adding the egg yolks. Eggs thicken as their proteins set, but if the mixture is too hot when the yolks go in, they scramble and turn grainy. Cooling it slightly first and then stirring over gentle heat keeps the sauce smooth.
