Why it works: Sugar and milk are a kitchen classic. They rank in the top 18% of all ingredient pairs, and cooks put them together in 77,875 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓

Shared aroma: 2-nonenal (fatty, green).
Sugar and milk barely smell alike, yet cooks put them together in 77,875 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Dissolves and sets into a smooth, sweet icing as it cools and thickens.
- Milk
- Dissolves the sugar and adds moisture so the syrup can be boiled to the right stage.
The step that matters
Remove from heat and stir until smooth and white. Stirring a boiled sugar syrup as it cools encourages tiny sugar crystals to form, which makes the icing creamy rather than grainy. Stirring too early or too late changes the texture.
