What each ingredient does

Milk
Forms the liquid base that gives the sauce its body and smooth, creamy mouthfeel.
Grated chocolate
Provides the main chocolate flavor and helps thicken the sauce as it melts into the liquid.
Egg yolks
Thicken the sauce as their proteins set with gentle heat, and add richness.
Sugar
Adds sweetness and balances the bitterness of the chocolate.
Rich cream
Adds fat for a silkier texture and a richer, rounder mouthfeel.

The step that matters

Thickening the mixture over heat. Once the custard base is back on the heat, keep stirring and avoid boiling. Egg yolks thicken by setting as they warm, and too much heat makes them scramble or curdle, leaving a grainy sauce.
