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
- Dissolves into the milk and sets into a sweet, creamy frosting as it cools and is beaten.
- Milk
- Dissolves the sugar and provides the liquid that cooks into a soft, creamy texture.
- Butter
- Adds fat for smoothness and richness in the finished frosting.
The step that matters
Cook without stirring for 12 minutes. Stirring while the sugar syrup boils can encourage sugar crystals to form, leading to a grainy frosting. Letting it cook undisturbed helps it reach the right concentration to set smoothly once beaten.
