Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Heavy cream
- Whipped into a stiff foam that gives the frosting its light, airy body.
- Eggs
- Add richness and help bind the mixture into a smooth, cohesive frosting.
- Sugar
- Adds sweetness and helps stabilise the whipped cream so it holds its shape.
- Melted butter
- Adds fat for richer flavour and a smooth, creamy mouthfeel.
The step that matters
Cooling the melted butter before stirring it in. Hot melted butter can melt and deflate the whipped cream, so letting it cool somewhat keeps the frosting thick and airy when it is folded in.
