Why it works: Cream and butter are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Carmel Icing
Ingredients
Directions
Boil the brown sugar, sweet cream, and butter until it reaches the soft ball stage.
Cool the mixture until it is warm to the touch, then beat in the vanilla.
If the icing is too stiff, add a little more cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides sweetness and caramel flavour, and sets the icing's body as it cools.
- Sweet cream
- Adds moisture and softness, loosening the icing so it spreads smoothly.
- Butter
- Adds fat for richness and a smooth, creamy texture in the finished icing.
The step that matters
Cool before beating in the vanilla. Beating the icing while it is still too hot can make it grainy or cause it to set unevenly. Letting it cool until warm to the touch lets the sugar crystals form a smooth, creamy texture.
