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

What each ingredient does

Egg
Thickens the sauce as it heats, giving it body without added starch.
Milk
Forms the liquid base that carries the chocolate and sugar and sets with the egg.
Grated chocolate
Provides the chocolate flavour and dissolves into the milk to colour the sauce.
Sugar
Adds sweetness and helps dissolve the chocolate into the milk.

The step that matters

Stirring the egg mixture on the heat without boiling. Egg proteins set when heated, so the sauce thickens, but if it boils or gets too hot the eggs scramble and the sauce curdles. Stir gently and keep it below boiling.
