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

What each ingredient does

Chocolate
Provides the main flavour and, once melted into the cream, the body of the frosting.
Egg
The yolk enriches and thickens the frosting, while the folded-in white adds lightness.
Confectioner's sugar
Sweetens the frosting and stiffens it to the desired consistency.
Scalded cream
Melts the chocolate smoothly and adds moisture and richness.
Butter
Adds fat for a smooth, glossy texture and richer mouthfeel.

The step that matters

Fold in the well-beaten egg white. Folding keeps the whipped egg white's air intact, so the frosting stays light. Stirring it in vigorously would deflate the foam and make the frosting denser.
