Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chocolate
- Provides the main flavor and body of the frosting once melted.
- Egg yolk
- Adds richness and helps emulsify the cream and butter into a smooth frosting.
- Confectioners' sugar
- Sweetens the frosting and thickens it to a spreadable consistency.
- Cream
- Adds moisture and softness, loosening the chocolate into a spreadable mixture.
The step that matters
Stir in confectioners' sugar until the right consistency to spread. Sugar stiffens the frosting as it is added, so adding it gradually and stopping at a spreadable texture prevents it from becoming too thick or too loose.
