Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Sweetens the icing and helps it set firm as it cools and thickens.
- Butter
- Adds fat for a smooth, rich texture and a glossy finish.
- Milk
- Provides liquid that dissolves the sugar and cooks into a creamy base.
- Grated chocolate
- Supplies the chocolate flavor and color of the icing.
The step that matters
Beating while cooling. Beating the hot mixture in cold water cools it while sugar crystallizes, so it thickens into a spreadable texture. Stopping too early leaves it runny, while waiting too long can make it stiff and grainy.
