Why it works: Sugar and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat and richness, and its softened fat holds the air beaten into the mixture.
- Sugar
- Sweetens the sauce and, beaten with the butter, helps form the air bubbles that make it light.
- Hot water
- Adds moisture and warmth, loosening the mixture so it can be whisked into a smooth, airy foam.
The step that matters
Stir continuously in one direction until a very light foam forms. Steady stirring in one direction traps small, even air bubbles. Stopping early leaves the sauce dense, while over-beating can deflate it or make it greasy as the butter separates.
