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

What each ingredient does

Sweetened vanilla chocolate
Provides the chocolate flavor and fat that give the frosting its richness and body.
Milk
Adds moisture and creaminess, helping the chocolate melt into a smooth, spreadable mixture.
Sugar
Adds sweetness and helps give the frosting a smooth, glossy texture as it sets.
Egg
Enriches the frosting and helps it thicken slightly as it cools.

The step that matters

Stir in the egg once the mixture is half cooled. If the mixture is still very hot, the egg can scramble into lumps instead of blending smoothly. Waiting until it has cooled partway lets the egg mix in evenly and thicken gently.
