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

What each ingredient does

Grated chocolate
Supplies the main flavor and cocoa fat that give the paste its body.
Corn starch
Swells when heated with the liquid, thickening the mixture into a stiff paste.
Eggs
Egg yolks enrich the paste and help it set as it cooks.
Sweet milk
Forms the liquid base that the starch thickens into the paste.
Sugar
Adds sweetness and softens the bitterness of the chocolate.

The step that matters

Stir constantly while the mixture boils and thickens. Starch thickens only once it reaches a boil, and it can scorch on the bottom of the pan or form lumps if not stirred continually. Constant stirring keeps heat even and the paste smooth.
