Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Provides sweetness and, once boiled, forms the body of the frosting as it cools and thickens.
- Milk
- Dissolves the sugar and adds moisture and richness to the frosting.
- Butter
- Adds fat for a smoother texture and richer flavor.
The step that matters
Boil without stirring for 12 minutes. Stirring during boiling can cause sugar crystals to form, making the frosting grainy. Boiling without stirring lets the mixture concentrate evenly so it can thicken properly when beaten.
