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
- Granulated sugar
- Caramelizes as it heats, providing the sauce's sweetness and deep amber flavor.
- Milk
- Adds moisture and dairy richness, softening the sauce's texture as it boils.
The step that matters
Boiling without stirring. Once the mixture boils, stirring can introduce crystals and make the sugar grainy. Letting it boil undisturbed for 4 minutes allows water to evaporate and the sugar to thicken and darken into a smooth sauce.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
